oh yeah speaking of the intake tube, for me it was very difficult to remove for the first time. since i didn't want to scratch the plastic. there're these tabs on one end where the tube meets the intake box. it was stuck there so snug it took me forever lol. i had to use lube and gentle pry it out with a flat screwdriver. afterwards i sanded down the tabs a little with a dremel and everything is easy to put on and off.

and also with the two plastic expanding pins, there are two pins for each side and the pin goes through the expanding "thingys" so total 4 pieces. DONT LOSE THEM! lol
