The aFe Power Momentum GT Pro 5R Cold Air Intake provides an impressive +102% airflow increase over stock, allowing the N20 engine to breathe and perform to its greatest potential. The Pro 5R filter consists of an oiled 5 layer mesh cotton gauze media for maximum performance and filtration. The Pro 5R maintains a 98. 6% efficiency rating, allowing high air flow and optimal performance even when dirty. A custom CAD designed roto molded housing made of black, cross linked, heat resistant polyethylene material eliminates the use of multiple components and ensures the coolest air intake charge available. A large clear sight window allows for filter inspection without removal of the airbox. The auxiliary air inlet allows for the maximum amount of air available for the intake. This system uses a high quality plastic CAD designed, dyno tuned, roto molded intake tube to achieve maximum power gains while maintaining a perfect fit. This Momentum GT intake system was designed around the largest filter possible to allow maximum performance and filtration. This cone filter has a large 4" flange and is 6 1 2" tall. The Pro 5R performance air filter features 5 layers of progressively finer mesh cotton gauze oiled media for better air flow, and is constructed with 100% polyurethane frame for long life and multiple cleaning cycles. Premium stainless steel clamps and a silicone coupling are used for strength and durability while also providing the most secure installation available. Momentum GT intakes are designed with fewer parts for a quick and simple installation.
