MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C\/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes.

This revolutionary design dramatically reduces the chances of any pressure leakage from the cylinders. An increased thickness in the gasket is introduced around vital sealing areas and the design of this extra layer forms a much stronger barrier to prevent gasses \/ pressure \/ water and oil escaping from its designated area. The layer acts as a very reliable defence and is highly recommended for any Subaru, specifically those running above the standard factory torque \/ horsepower figures.\u003c\/p\u003e  \u003cp\u003eIn conjunction with this new technology our gaskets also feature a unique nitrile rubber coating. This coating is designed to act as a cushion in which to fill \/ take up any areas of imperfection found in either the cylinder head or block faces, to ensure you have the very best combustion chamber armour!\u003c\/p\u003e  \u003cp\u003eFinally our cylinder head gaskets are all stamped from dies as appose to laser cut. With die stamping you can process a large amount of material at once which means that variations in the quality of each individual gasket is far less compared to laser cutting (in which each gasket section is cut separately to one another). With Die Cutting the finished edges are also far superior, leaving a much smoother, neater edge to the gasket as appose to laser cut steel which leaves a sharper edge behind.\u003c\/p\u003e  \u003cp\u003eFor the ultimate seal all our gaskets are manufactured and designed to accept the larger 12mm and 14mm cylinder head studs also available from our online store. The standard cylinder head bolt (the component that joins the cylinder head to the block and offers force to seal your cylinder head gasket in place) is 11mm thick and uses a relatively fine thread. It is important to remember this bolt was developed for use on a mainstream engine producing no more than 320Bhp, Subaru did not manufacture this bolt for use with anything above this power and as such it is important to consider stronger and more suitable replacements. Here at RCM we manufacture both a 12mm and 14mm replacement head stud and nut kits. The studs are naturally stronger due to their extra thickness and superior material quality but they also benefit from a much coarser rolled thread (meaning you can tighten them far more than the standard bolt which in turn will offer a much higher clamping load between both the cylinder head and block faces where you head gasket is situated.)\u003c\/p\u003e  \u003cp\u003eReliability is key to any engine rebuild, whether done for higher horsepower applications or just a simple repair \/ refresh its important to choose your components wisely so that you don’t end up repeating the process later down the line.\u003c\/p\u003e  \u003cp\u003e• Available Sizes: 0.78mm | 1.1mm | 1.5mm\u003c\/p\u003e  \u003cp\u003e• Fitment: EJ25 (2006+)\u003c\/p\u003e  \u003cp\u003e• 14mm Diameter Head Stud \/ Bolt Holes (Also suitable for use with Standard Head Bolts and 11mm Stud Kits\u003c\/p\u003e  \u003cp\u003e• Die Cut\u003c\/p\u003e  \u003cp\u003e• Folded Stopper Layers\u003c\/p\u003e  \u003cp\u003e• Multi Layer Steel Gasket (MLS)\u003c\/p\u003e  \u003cp\u003e• Nitrile Rubber Coated\u003c\/p\u003e  \u003ch2\u003e# KEY FEATURES\u003c\/h2\u003e  \u003cp\u003e• Improved sealing capacity over conventional gaskets thanks to its Nitrile Rubber Coating.\u003c\/p\u003e  \u003cp\u003e• Increased protection around combustion chambers by means of its Folded Stopper Layers.\u003c\/p\u003e  \u003cp\u003e• Die Cut precision manufactured for the highest quality finish and fitment.\u003c\/p\u003e  \u003cp\u003e• Ready for immediate use our larger 12mm \u0026amp; 14mm head stud kits\u003c\/p\u003e  \u003cp\u003e• Complete range of sizes available for all EJ20, EJ22, EJ25, EJ25+ series engines.\u003c\/p\u003e \u003ca href=\"https:\/\/www.prospeedracing.com.au\/Roger-Clark-Motorsport-EJ25-Multi-Layer-Head-Gasket-1.1mm-PAIR-Subaru-WRX-STI-FXT-LGT-08-RCM1693\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e","brand":"Roger Clark Motorsport (RCM)","offers":[{"title":"Default Title","offer_id":67902502568256,"sku":"RCM1693-PAIR","price":365.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0985\/1152\/0064\/files\/RCM1693-PAIR_42f38774-eced-49d6-91cd-44739d072ceb.jpg?v=1793260689"},{"product_id":"iag-performance-arp-14mm-head-stud-set-iag-eng-1711","title":"IAG Performance ARP 14mm Head Stud Set IAG-ENG-1711","description":"\u003ca href=\"https:\/\/www.prospeedracing.com.au\/IAG-Performance-ARP-14mm-Head-Stud-Set-Subaru-WRX\/STI\/FXT\/LGT-EJ20\/EJ25\/FA20DIT-IAG-ENG-1711\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e\u003cp\u003eIAG's \/ ARP 14mm Head Stud Set is designed for use on high horsepower Subaru engines.

This solution is loosely derived from diesel technology where a counterbore step is machined around each cylinder bore allowing specially sized fire rings to drop into the machined area and head gasket bores. The shims are designed to create a compression seal once the heads are installed and torqued into place. IAG fire rings are manufactured to a very strict tolerance from a proprietary alloy and are then put through a heat treatment process. The gaskets are manufactured from an asbestos-free composite raw material and feature a silicone based beading applied to critical areas to improve sealing around all water and oil passages.

Unlike most conventional cylinder head gaskets, our gaskets use what is most commonly known as a Ðfolded stopper levelÓ. This revolutionary design dramatically reduces the chances of any pressure leakage from the cylinders. An increased thickness in the gasket is introduced around vital sealing areas and the design of this extra layer forms a much stronger barrier to prevent gasses \/ pressure \/ water and oil escaping from its designated area. The layer acts as a very reliable defence and is highly recommended for any Subaru, specifically those running above the standard factory torque \/ horsepower figures.  In conjunction with this new technology our gaskets also feature a unique nitrile rubber coating. This coating is designed to act as a cushion in which to fill \/ take up any areas of imperfection found in either the cylinder head or block faces, to ensure you have the very best combustion chamber armour!  Finally our cylinder head gaskets are all stamped from dies as appose to laser cut. With die stamping you can process a large amount of material at once which means that variations in the quality of each individual gasket is far less compared to laser cutting (in which each gasket section is cut separately to one another). With Die Cutting the finished edges are also far superior, leaving a much smoother, neater edge to the gasket as appose to laser cut steel which leaves a sharper edge behind.  For the ultimate seal all our gaskets are manufactured and designed to accept the larger 12mm and 14mm cylinder head studs also available from our online store. The standard cylinder head bolt (the component that joins the cylinder head to the block and offers force to seal your cylinder head gasket in place) is 11mm thick and uses a relatively fine thread. It is important to remember this bolt was developed for use on a mainstream engine producing no more than 320Bhp, Subaru did not manufacture this bolt for use with anything above this power and as such it is important to consider stronger and more suitable replacements. Here at RCM we manufacture both a 12mm and 14mm replacement head stud and nut kits.

Unlike most conventional cylinder head gaskets, our gaskets use what is most commonly known as a Ðfolded stopper levelÓ. This revolutionary design dramatically reduces the chances of any pressure leakage from the cylinders. An increased thickness in the gasket is introduced around vital sealing areas and the design of this extra layer forms a much stronger barrier to prevent gasses \/ pressure \/ water and oil escaping from its designated area. The layer acts as a very reliable defence and is highly recommended for any Subaru, specifically those running above the standard factory torque \/ horsepower figures.  In conjunction with this new technology our gaskets also feature a unique nitrile rubber coating. This coating is designed to act as a cushion in which to fill \/ take up any areas of imperfection found in either the cylinder head or block faces, to ensure you have the very best combustion chamber armour!  Finally our cylinder head gaskets are all stamped from dies as appose to laser cut. With die stamping you can process a large amount of material at once which means that variations in the quality of each individual gasket is far less compared to laser cutting (in which each gasket section is cut separately to one another). With Die Cutting the finished edges are also far superior, leaving a much smoother, neater edge to the gasket as appose to laser cut steel which leaves a sharper edge behind.  For the ultimate seal all our gaskets are manufactured and designed to accept the larger 12mm and 14mm cylinder head studs also available from our online store. The standard cylinder head bolt (the component that joins the cylinder head to the block and offers force to seal your cylinder head gasket in place) is 11mm thick and uses a relatively fine thread. It is important to remember this bolt was developed for use on a mainstream engine producing no more than 320Bhp, Subaru did not manufacture this bolt for use with anything above this power and as such it is important to consider stronger and more suitable replacements. Here at RCM we manufacture both a 12mm and 14mm replacement head stud and nut kits. The studs are naturally stronger due to their extra thickness and superior material quality but they also benefit from a much coarser rolled thread (meaning you can tighten them far more than the standard bolt which in turn will offer a much higher clamping load between both the cylinder head and block faces where you head gasket is situated.)  Reliability is key to any engine rebuild, whether done for higher horsepower applications or just a simple repair \/ refresh its important to choose your components wisely so that you don?t end up repeating the process later down the line.\u003ca href=\"https:\/\/www.prospeedracing.com.au\/Roger-Clark-Motorsport-EJ22-Multi-Layer-Head-Gasket-1.1mm-PAIR-Subaru-WRX-STI-FXT-LGT-08-RCM1791\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e","brand":"Roger Clark Motorsport (RCM)","offers":[{"title":"Default Title","offer_id":67903058379072,"sku":"RCM1791-PAIR","price":483.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0985\/1152\/0064\/files\/RCM1791-PAIR.jpg?v=1793264512"},{"product_id":"grimmspeed-multi-layer-mls-head-gasket-pair","title":"Grimmspeed Multi Layer MLS Head Gasket PAIR","description":"\u003ca href=\"https:\/\/www.prospeedracing.com.au\/Grimmspeed-Multi-Layer-MLS-Head-Gasket-PAIR-Subaru-WRX-06-14\/STI-06-07\/FXT-03-08-EJ25-12400A\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e\u003cp\u003e\u003cstrong\u003eSEAL the deal with a set of GrimmSpeed EJ25 Head Gaskets!\u003c\/strong\u003e\u003c\/p\u003e  \u003cp\u003eGrimmSpeed has set the standard for quality when it comes to aftermarket replacement gaskets so it’s only natural that we should offer our fans the MOST important gaskets their car will ever need: Introducing The GrimmSpeed EJ25 Head Gasket Sets!\u003c\/p\u003e  \u003cp\u003eFeature-packed, these gaskets are a perfect fit for any engine build, from basic refresh to a high horsepower track monster.\u003c\/p\u003e  \u003cp\u003eThe GrimmSpeed Head Gaskets feature a multi-layer steel (MLS) construction, in which multiple grades are used to provide optimal surface and combustion chamber sealing as they are torqued down. The top and bottom layers feature a Nitrile Rubberized Coating that helps accommodate a rougher RA surface finish of up to 50microinch. This acts to better seal the non-critical areas of the gasket. In addition, the gasket edge includes a folded stopper layer that allows for optimal sealing for the combustion chamber. This is done to help reduce the chances of combustion gasses causing head gasket failures under extremely high cylinder pressures that built engines can experience.\u003c\/p\u003e  \u003cp\u003eAfter talking to numerous engine builders\/tuners it was clear that creating a variety of gasket thicknesses was key for pairing them with the right build. With that in mind, we’ve made the gaskets available in multiple thicknesses (.78, 1.1, 1.5mm) to help fine tune each individual build. In addition, the slightly oversized bore diameters will allow for up to 0.5mm overbore.\u003c\/p\u003e  \u003cp\u003eThe EJ specific gaskets include enlarged center head bolt holes to accommodate up to a 13mm head studs.

This is done by using a unique gasket design feature which sets us apart from the competition. By strategically undercutting the middle layer of the gasket near the combustion chamber, we can control the crushing of outer layers, which in turn creates a perfect seal around the combustion chamber.  \u003c\/p\u003e  \u003cp\u003eWe can visually demonstrate this feature by using pressure sensitive film and compressing the gasket in a manner which mimics the tightening of a head against the block. The film changes colors from white to pink to red as pressure is applied to denote areas of high and low pressure application. This information will then allow for easy visual verification of effectiveness in sealing of a gasket against a surface.\u003c\/p\u003e  \u003cp\u003eAs seen in the results, the combustion chambers are sealed evenly and equally around the circumference of the cylinder by the deep part circles. This visual representation is showing that combustion gasses are going to be held in the chamber and directed towards pushing the piston instead of escaping. Failure of a gasket to seal with even pressure around the circumference of the cylinder would be detrimental for performance and reliability of a gasket and would most certainly result in failure.  \u003c\/p\u003e  \u003cp\u003eWhen combining the perfect sealing, nitrile coating and other features of the gaskets, we are able to ensure that your engine build is ready for anything that you throw at it.

This solution is loosely derived from diesel technology where a counterbore step is machined around each cylinder bore allowing specially sized fire rings to drop into the machined area and head gasket bores. The shims are designed to create a compression seal once the heads are installed and torqued into place.
