Took me and hour maybe hour and a half. Skill level-Medium, (Installed CAI on other mods on my MSP).--->If i cant get it off i break it off or cut it off! (hand) I took a look at the pics people have posted on the forums, which helped a lot. The biggest pain in the ass was that air direction thingy in front of the drivers side, wheel just behind the fog light. I simply popped the pins holding it to the left side then jerked the s*** out of it (left and right rotating it) until I could get a good angle at the screw which is recessed and WAY at the top. That thing took me about 20 mins to get off. After peeling back the wheel well liner it was fairly simple. The install of the CAI really easy. The hardest part is taking all the stuff OFF the car prior to installing. Now its time for(cheers). Need help with anything PM me.
