The Turner Motorsports Performance CSL Air Filters are a multi-layer synthetic dry 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 Synthetic High Flow Air Filter. These filters can be cleaned and reused for an extended service life.

Oiled versus Dry Filters:

• Although both options will keep the air to your engine clean and improve airflow, there are a few differences to consider when choosing the best filter for you. Oiled filters allow better airflow than dry filters, however they require more maintenance. Oiled filters will likely get dirty faster, needing to be cleaned more regularly. When cleaning an oiled filter, it is necessary to oil them with filter oil afterwards.
• Dry filters offer slightly lower airflow but are easier to maintain while still out performing the OE paper filter. Dry filters can be washed with warm soapy water. There is no oiling necessary afterwards.
• Both dry and oiled filters flow better than stock and can be reused.
