A new oxygen sensor set can improve driveability and lengthen engine life. Ultimately, you achieve a smoother running engine that is more fuel efficient. Feedback from the oxygen sensors provides closed-loop control of the injected quantity of fuel for optimum air-fuel mixture, enabling virtually complete combustion to take place. Contaminants in gas and certain atmospheric conditions can drastically shorten the life of any oxygen sensor, therefore they should be checked with every periodic maintenance and changed if necessary. Sold separately, but four sensors are required. Fits E36 front and rear, M Roadster / Coupe front to 2000. Bosch Part # 13 884. Also replaces 11781437943. This item fits the following BMWs: 1996-1999 E36 BMW 323is 323ic 328i 328is 328ic M3 1997-1998 E39 BMW 528i 1998-2002 Z3 BMW Z3 M Roadster M coupe

The OEM plastic PCV valve does not hold pressure well even when brand new. What this means is that when the turbochargers are making boost, pressurized air can become forced backwards through the valve and back into the crankcase. Depending on the condition of your PCV valve this can range from irritating to dangerous as a pressurized case can cause all sorts of issues. Additionally, if your valve cover is cracked due to age or has a bad gasket you are more than likely experiencing a pressure leak either internally or externally. These two features can cause even a low-mileage N54 to run like a tired elephant, sometimes even unlocking a special bonus function known as "Limp Mode". The solution is to replace any failed components and upgrade the PCV valve to something more capable withstanding the abuse of a turbocharged environment. FTP Motorsport has you covered with this solid aluminum valve assembly. It is essentially the same thing that came in your car from the factory, made out of aluminum. The internal components have also been made to fit tighter and outlast the life of an off the shelf replacement. No, this won't be the very last PCV valve you buy, but it will most certainly alleviate a lot of headaches common to N54 owners. And if you're tuned, big twin or single swapped you need one of these yesterday.

This is the secondary air pump valve for E9x M3 with the S65 V8 engine. Over time carbon builds up inside the secondary air pump valve causing it not to close properly. This failure to close properly can allow exhaust and moisture to get past the valve and enter the secondary air pump, leading to premature pump failure.

This air pump check valve prevents exhaust gases from entering the air injection system. If the air injection check valve develops issues, then the check engine light can illuminate. This issue will cause your vehicle to release more emissions and potentially damage the AIR system. Replace your old malfunctioning valve to get your car emissions compliant again.
