The Turner Motorsports Performance CSL Air Filters are a multi-layer oiled cotton construction that contains millions of smaller fibers to provide superior filtration and performance over the OEM filter. Precisely manufactured for a secure fitment to ensure all the air entering your motor is properly filtered. With the CSL E46 only being offered in Europe, the OEM air filters are produced in much lower quantities making them harder to obtain and drive up the price. Turners solution is a price effective filter that offers premium filtration with increased flow with extended service interval and lifespan.
Having a clean air filter ensures your engine is running at its best efficiency! Proper air flow will help your engine breathe, get the best fuel economy and allow full power throughout the power band. Get the most out of your CSL intake with a new Oiled High Flow Air Filter. These filters can be cleaned, oiled and reused for an extended service life.
