S&B gives you the freedom to choose from their traditional oiled cotton filter media, or if you have always wanted a high quality performance filter that you could just throw way instead of having to clean and re-oil it, now you install their disposable dry filter. Best of all, you don’t have to sacrifice performance and engine protection if you choose their dry filters, and the dry filters last for up to 30,000 miles of highway driving and filter life can be extended even further if cleaned occasionally with compressed air. Extensive airflow and filtration efficiency testing shows comparable results from S&B’s oiled and dry intake filters, so the choice is yours!

This S&B intake increases airflow by 47.2% over your stock intake system and boasts a 99.68% filtration efficiency rate. That means the good air gets in, and the dirt stays out.
