In 1999 Injen designed the first urethane filter with a built in velocity stack for added performance. Quality engineering!
Fujita's Super Flow High Performance Air FilterT was designed to maximize efficiency without compromising filtration.
Now that you have that aftermarket Short Ram Intake be sure to keep the increased filtration and maximized air flow with a replacement Airinx Air Filter.
The SPW replacement air filters offer great quality with an extremely low price. Their free flowing proven design is enhanced with a unique funnel shape and comes pre-oiled so installation is a snap.
