RE: Front Spoiler Clearance
You do need to be careful working around the engine bay though. When I put my CAI on, I kept running my feet into the front spoiler. When you are close enough to actually reach into the engine bay, your feet are actually underneath the spoiler.
Driving wise, I haven't had a problem. Watching it come off the truck was a nightmare though. The spoiler must have had 1 inch clearance max. The driver was very careful, but still quite nerve racking.
