Installed a Volant CAI (18857) on my '08 Tundra 5.7 today. Couple of points (and let me know if I am being a little too anal). First off, the install took approx 1 hour, and the only reason being is I double and triple checked the MAF orientation, and all fasteners. Also..I noticed the new box does not completely cover the hole in the fender for fresh air intake. (Just a slight difference). And finally, the set screw for the plastic engine lid is just a little too long. (Minor oversight by the engineers @ Volant). To me, attention to detail goes a long way. Will test the power tonight on the way to work.
