The RENNtech Performance Carbon Fiber Airbox is meticulously crafted for the Mercedes V8 Kompressor engine, specifically those utilizing the M113 engine code.

The RENNtech Carbon Fiber Airbox is designed to be a direct fit for various Mercedes-Benz models including the C219 CLS 55 AMG Kompressor (2005-2011), as well as compatible with the E55 AMG Kompressor (211 chassis) and CL 55 AMG Kompressor (215 chassis).
