PLM Power Driven Heat Exchanger – Audi S4 / Audi S4 / Audi A4 / Audi A4

PLM Power Driven Heat Exchanger – Audi S4 / Audi S4 / Audi A4 / Audi A4

SKU: PLM-AUDI-B8-HE

The PLM Power Driven Heat Exchanger is engineered to combat one of the biggest limitations of supercharged Audi performance — heat. As boost levels rise and driving becomes more aggressive, intake air temperatures quickly increase, forcing the ECU to reduce timing and power. Upgrading to a larger, more efficient heat exchanger is one of the most effective ways to maintain consistent horsepower.

This proven PLM design has been trusted by enthusiasts for years and remains one of the best values available. Featuring a massive furnace-brazed aluminum core, precision TIG welding, and CNC-cut mounting brackets, this unit dramatically improves thermal capacity while retaining a straightforward installation.

With a frontal surface area increase of approximately 135% over the factory unit and over 417 square inches of fin coverage, the system delivers faster heat dissipation, improved resistance to heat soak, and more repeatable performance during spirited driving or track sessions.

Why You Need It

When intake temperatures climb, power drops. By improving the cooling system’s ability to reject heat, the PLM exchanger helps:

• Maintain horsepower

• Support tuned or higher boost vehicles

• Improve recovery between pulls

• Deliver more consistent throttle response
