Oiled vs. Dry Filters — Which Is Right for You?

Oiled Filters

Require more frequent cleaning

Must be re-oiled after each cleaning

Long-term reusable design saves money over disposable paper filters

Dry Filters

Provide excellent airflow with minimal maintenance

Easily cleaned with warm, soapy water—no oiling required

Still flow significantly better than OE paper filters

Fully reusable and cost-effective

Both versions deliver superior performance over stock filters while offering the long-term benefit of reusability. Choose the option that best fits your maintenance style and performance goals.

In BMW's with the B46 engine, the intake system is partially limited. The bottom portion is lightweight and great for feeding cold air to the intake, but the top portion is excessively restrictive. Working with some of the original equipment, this intake continues to utilize the bottom portion of OE ducting and heat shielding, but replaces the top with a new high flow inverted performance cone filter. Extensive testing showed up to a 10+ HP gain to the wheels and allows for quicker turbo spool speed. Plus, this design gives you a great sound improvement, letting you hear both the intake and the turbo spooling!
