Went really well. Intake just about jumps out of engine bay if you disconnect the "ball bracket" from below before you try to take the intake out....tons of room with that out of the way. I left it out as well, doesn't look like it serves a purpose except for the factory intake.
I've read the Injen intake makes too much noise. It is out of the question for me unless they get a CARB EO# for it anyways. Furthest I'd go is a filter swap for now, unless I want to swap in the OE intake for smog checks, (not fun)!
