I do not like the Injen for the RA
I am a big fan of the Injen intake, but not for the RA. I love their intake for the Evo X (best IMO), and their intake for the Evo 8/9 (second best). But on the RA they dropped the ball. That rubber hose is a disaster. It is too soft and seems to collapse under suction especially when you increase the boost on the car. On Gear Grinder's car, it lowered the load numbers logged. That told me that something was wrong. I think the collapsing hose has something to do with. GG removed the Injen and went back to stock. The car recovered a lot of the lost load.
I do not know why Injen cheaped out and used rubber hose instead of an all aluminum design.
