Overall solid, the screw with the rubber piece however did not fit well on the original mounting bracket. This made alignment of all the valves slightly difficult. Also the temperature sensor seems to fit a little loose. Was not a very hard process, but the written instructions and pictures did not help much in terms of assuring I was doing things correctly. Would help to include clarification on what a leak would sound like versus intended sound.
Tremendous improvement over the stock airbox
I purchased the Injen intake to replace the stock airbox not for increased performance but because of a broken output nipple on the stock unit. I chose the Injen because it has an Amsoil filter. The build quality is robust and it's absolutely beautiful. I'm thoroughly pleased with my purchase.
