VCTR Performance BMW M240i/M340i B58 Heat Exchanger Upgrade

Overview

The B58's water-to-air charge cooling system uses a front-mounted heat exchanger to manage charge air temperatures. Under sustained boost — particularly on tuned applications — the factory heat exchanger becomes a thermal bottleneck. This upgraded unit provides improved coolant heat exchange capacity for more consistent charge temperatures.

Why Upgrade?

• Improved heat exchange capacity over the factory heat exchanger
• Better charge air temperature consistency on sustained boost
• More consistent performance on tuned B58 applications
• Black finish — direct replacement installation

Engineering Focus

Front mount heat exchanger with improved core capacity over the OEM unit. Black finish for underbonnet presentation. Covers multiple G-series and J29 B58 chassis.
