Help with notching the bumper

[mikeroy420]

Hey guys, my greddy rspl intercooler kit didnt come with any instructions, so can someone tell me what size holes you made for the piping and how much of your bump did you notch(deminsions)? Thanks for the help

I'd measure the piping (2.5" i think) and cut your holes 1/2" larger than the outside diameter of the piping. As for the bumper, you install the IC then try to put the bumper on and trim it down until it bolts back on. Start with that. Everything in life doesn't come with instructions.
