I just bought a Si 08 Sedan and am considering the Injen CAI system. I would appreciate some info for those who have installed them. Thanks!

 

Ehhh...

not to be rude, but you should ask a question if you want an answer.

 

injen is by far the best cai brand, i bought a AEM cold air intake and i sent it back because it didnt fit correctly. and when i had the two of them in either hand when i was doing to swap i could totally feel the difference in quality craftsmanship.. id recommend the injen cai hands down

 

i would go with injen
