The PLM Heat Exchanger Cooling Kit PLM-ME55-HX-JP-WW is a complete cooling solution for Mercedes-Benz E55 and CLS55 AMG supercharged 5.5L engines. Designed for bolt-on installation, this all-in-one kit dramatically reduces intake air temperatures (IAT), helping you maintain horsepower and engine reliability under extreme driving conditions or increased boost.
The PLM heat exchanger features a non-epoxied furnace-brazed core, CNC-machined billet aluminum necks, and a massive 4000 square inches of fin surface area with 1.8 liters of fluid capacity. The included Johnson CM30 electric pump with plug-and-play harness improves coolant circulation, and the Redline Water Wetter enhances thermal efficiency even further.
