PLM Mercedes Benz 5.5L AMG Heat Exchanger – Mercedes-Benz E55 AMG / Mercedes-Benz CLS55 AMG / Mercedes-Benz SL55 AMG

SKU: PLM-ME55-HEAT-EXCHANGER

When it comes to controlling intake temperatures on the supercharged 5.5L AMG platform, cooling efficiency is everything. The PLM Power Driven Heat Exchanger is a proven solution trusted by enthusiasts for over a decade, designed to combat heat soak, stabilize intake air temps, and help your AMG maintain consistent power during aggressive driving or hot weather conditions.

Factory systems can quickly become overwhelmed, especially on vehicles running increased boost or additional performance upgrades. By expanding cooling capacity and improving airflow across the core, this upgraded unit helps keep temperatures down so the engine can deliver repeatable performance pull after pull.

PLM utilizes a non-epoxied furnace-brazed core for superior durability and heat transfer, paired with CNC-machined billet aluminum necks and precision welding. The result is a high-quality, direct-fit component that mounts in the OEM location while dramatically improving cooling efficiency.

Why Upgrade?

Lower intake air temperatures mean the ECU can maintain optimal timing and power output. Instead of losing performance as temperatures climb, your AMG stays stronger and more consistent.
