hey i put a testpipe on a few months back from p2r, and ive had a C.E.L since i put it on but im kinda tired of seeing that light, so i was wondering what is the exact part number for the defouler, because i just went to auto zone but they had a bunch of diff sizes and im not to sure of which one to get, plus i read that i had to drill it out? could someone explain more for me. thx

They also sell 90 degree adaptors on ebay for like $18 in case you want to go the easy route (not that the above mentioned procedure is that hard). I just picked one up as I dont feel like bending/cutting the heat shield as the o2 sensor would stick out further with the regular de-fouler deal.

 

true but idk im planning on doing this tomorrow and dont feel like waiting to order one, so what size did you use to bore it out?

 

and also did you use the gasket that come with it? or i dont need those?

 

This is just what I needed! I have the stuff sitting in my garage, but wasn't sure how to do it. Thanks!

 

there is enough room (at least there was on my car so that a 90deg wasnt needed)

I think its 1/2 inch

 

alright thx, do i need to use the washers that come with it, or their not needed?

 

not needed
