R2 Intercooler Pump Kit

The RennTech R2 Performance Package is designed as an entry-level performance enhancement for the Mercedes-Benz W221 S 65 AMG. This comprehensive kit builds upon the R1 package by incorporating a proprietary ECU tune, an upgraded intercooler pump kit with an additional cooler for improved efficiency, a distinctive 3-piece full carbon fiber airbox, and performance-tuned stainless steel mufflers. This results in an elevated driving experience without compromising the daily drivability and reliability expected of the S 65 AMG. The package pushes the output from a stock 621 HP and 738 LB-FT to an impressive 700 HP and 900 LB-FT at specific RPM ranges. Key features of the R2 Performance Package include the RennTech ECU Upgrade, the 3-piece Full Carbon Fiber Airbox, the RennTech High Flow Intercooler Pump Kit, and Stainless Steel Performance Mufflers. These components collectively contribute to increased engine performance, including a higher rev limiter, significant gains in horsepower and torque, and an improved throttle response.
