This is an OEM MAHLE fuel filter that removes dirt and other particle contaminants from your fuel.

A clogged fuel filter makes it difficult for your engine to get all the fueling it needs. Filters commonly clog from a deteriorating gas tank, bad fuel, or other debris in the fuel system. A fresh fuel filter addresses many fuel related problems including surging, stalling, cold start issues, and poor performance under a variety of conditions.

Modern brake systems, such as those featuring ABS and ESP®, are designed for improved performance to safely stop vehicles. With improved performance comes a higher load on the braking systems. These systems require a brake fluid with a high wet boiling point, low viscosity, and high lubricity. As a vehicle system developer and the first to market ABS and inventor of ESP®, Bosch understands the need for high-quality brake fluid. Bosch ESI6 is a next-generation brake fluid. It exceeds all current DOT standard requirements (FMVSS 116).
