The SP series intake system features the patent pending MR (MegaRam) Technology process for optimal gains and a safe A/F ratio. The SP series does not limit itself to just a Cold Air system or Short Ram System. The MR Technology process has its effects on both types. SP is The World's First Tuned Intake System.
We especially like the ability to convert between Cold-Air and Short Ram styles!
Injen claims power gains of up to 9.4 hp and 13.1 ft/lbs of torque.
