This Momentum GT intake system was designed around the largest filter possible to allow maximum performance and filtration. This cone filter has a large (6-3/4" x 4-3/4") oval flange and is 9" tall with an inverted top. The Pro 5R performance air filter features 5-layers of progressively finer mesh cotton gauze oiled media and is constructed with 100% polyurethane frame for long life and multiple cleaning cycles. The smooth one-piece high quality sealed housing with auxiliary air inlet is used to eliminate the use of multiple-piece housings and ensure the coolest air intake charge available. A large, clear sight window is used for a hassle-free filter inspection and an aggressive style. A urethane plug is also included if you wish to block off the auxiliary air inlet. This system uses a high quality, dyno-tuned intake tube to achieve maximum power gains while maintaining a perfect fit.
