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.
