The filter size and shape have been custom-designed just for these models to maximize the available surface area and permit more air into the engine. The stage 2 kits packs all of the filter technology of more expensive kits but in a more basic and straight-forward (budget friendly) package. Without a top cover the exposed air filter will drastically change the intake sound (for the better!) even with the heat shield.
The Pro 5R filter is an oiled-cotton gauze filter media - the 5-layer filter flows a lot better than a paper filter while a small coating of retention oil traps dirt, dust, and debris. The Pro 5R filter is washable and reusable and only needs occasional cleaning and re-oiling from an aFe service kit.
The Pro Dry S synthetic filter material is denser than the aFe Pro 5R so it does not require any dust-retention oil, yet it flows up to 66% more air than a conventional stock paper filter. The Pro Dry S gives you a modest power increase with excellent filtration (99.2% efficiency) but less maintenance than the oiled filter. The Pro Dry S is cleaned using an aFe service kit and regular tap water.
This intake, when installed on some of the models listed below, is approved for use in California under an Executive Order (EO, waiver). CARB EO# D-550-38.
