Be sure you turn the hose clamps where you have access to the nut. The Mass Air Flow sensors MUST go back in the same way they came out. forward facing forward. No exceptions! One of the K&N tubes I received, the port for the MAF was welded in backward . Engine just will not run right with this. K&N sent me a replacement tube, but I still had a lot of mental anguish and had to take the car to a shop to have the ECU reset. But that is rare. Don't let my experience with this deter you . ALSO, falcon fixer is right, they are still warm air. Not really any performance gain, no matter what they say. I saw a real test (England ) done on cold air intakes and there is really hardly any gain in performance. I just wanted the sound when accelerating hard, without the constant loud drone of aftermarket exhaust, nor the expense. I did get the sound, and I'm happy with the K&N .
Hope this helps.
