Hi, I have an S reg mk4 1.8 16v. I was thinking of de-restricting the airbox, and have heard of people drilling holes into the sides of the box, and also the inlet pipe.. i am not too keen on the idea of putting cold-air ducting to lots of holes on the airbox, so i was thinking of just a few holes on the front side of the pipe, where it lies next to the grille..
Has anyone done this? What will it sound like? (i have heard that holes in the airbox itself sound nice)
Any info would be great!
