Overview

This second-generation unit offers a significant flow rate increase of 8.7 GPM at 11.6 PSI, compared to the 3.00 GPM rate of the OEM pump.
Show original supplier description
The RennTech Intercooler Pump Upgrade Kit replaces the problematic OEM intercooler pump to provide substantially cooler charge air temperatures. By flowing over twice as much coolant as the factory unit, this kit enables a denser air/fuel mixture, helping the engine maintain peak performance levels across the entire operating range. This system is designed as a direct-fit component that mounts in the OEM location without requiring modifications, thanks to its lightweight and compact construction. The kit includes all necessary plumbing, electrical connectors, mounting hardware, and installation instructions for a complete installation. This upgrade is specifically engineered for the 2003-2006 Mercedes-Benz E55 AMG (W211) and related 55 AMG Kompressor models. It is built to resolve cooling limitations inherent in the factory system, ensuring sustained performance under demanding conditions.
