Re: Where do you fix the GTA mod pipe?
It is dificult to spot the fixing hole, but it will be there as its built into all 156 bodies. I struggled to find it myself until I removed the foglight.
The intake pipe should be positioned approximately vertically, coming out of the air filter case and pointing upwards, so that the intake pipe mounting hole is up behind the headlight.
If you follow the wiring loom from the foglight, you'll see it runs up behind the headlight and fastens to a metal upright. That's the same upright as the intake fastens to. If you unscrew the wiring harness fastening, it will help you see.
There are three holes in the upright. The foglight wiring fastens into one. There's another circular one nearby and then a square hole a bit above those two. At first, you can't believe its the right one, as its so high up the metal upright, but you'll see that the square nylon mounting plug just pushes nicely into the square hole....
Trust me - its there!
