This Momentum GT intake system outflows the factory intake by 24. 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. A custom high temperature reinforced silicone elbow coupling with aluminum fitting is included for easy install to the factory breather line.
