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 - 34 x 4 - 34) 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.
