This Momentum GT intake system produces 20hp, 23lbs x ft of torque, and outflows the factory intake by 38%. The one-piece sealed housing includes auxiliary air inlet 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.
