ok i got an invidia test pipe and i cant find the defouler for it the 18mm one at pepboys or auto parts are too small( 18mm is the size for the socket to tighten it i assume) caN ANY ONE HELP ME OUT THNKS....

 

I found mines at Discount Auto, the part# is 42009.

It should look like this.

 

Yep yep, used the same one. It's a bitch drilling out though, almost burned mine up

Also, be sure you drill it wide enough. The first time, I made it so there wasn't a whole lot of room between the sidewall and sensor, and threw a CEL about 5 miles later.

Drilled it out a little bit more, haven't had a CEL since, and that was about 2k miles ago


Have fun

 

thanks guys

 

Yo DSM I have a fabricated TP , do you think I can put a Defouler in mine ?

 

Does your Oxygen Sensor screw in with no problems? If so, then I don't think it should be a problem.

 

did you guys use the gaskets from the fouler

 

I didn't.

 

thanks again

 

The gaskets that it comes with aren't needed.
