aFe Momentum cold air intake kit for 135i/335i (N55). This kit uses the aFe Pro 5R oiled cotton gauze cone filter with a sealed factory-style airbox and tuned intake ducting. The Momentum kit replaces as much of the stock intake as possible in order to fit the largest air filter.
- 12hp gain
- 14ft-lbs gain
- Improved engine sound
- Synthetic oil-free filter
- Easy install
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 Momentum air box is then built around the filter to completely seal it away from engine heat. The air intake is completely redesigned to maximize air flow in the airbox and intake ducting, including using CAD and roto-molding to produce efficient designs using premium materials. The Pro 5R 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.Notice of Emissions Non-Compliance.
