Quick question, I've reviewed most of the DIY's on how to install HFC's on a G...I'm planning installing FI HFC's soon. I have Injen CAI on currently, am I gonna have to take the Injens out to reach some of the bolts in the engine bay? ( I didn't see any info about that anywhere)

 

Yea. You should deff take the whole airbox out. Gl with the 2 bolts on top of the header. Took 2 guys, alot of pb blaster, a ladder and lots of torching to break those suckers loose. This may help you out a bit. GL!
