Emissions System for BMW Z Series E85/6 (2003-2008)

When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem. 

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking. 

Bad oxygen sensors can cause check engine lights and poor fuel mileage. Replace your faulty sensor with this high quality Bosch sensor to turn off your check engine light and restore fuel mileage.
