I just picked up a set of Berk test pipes for my 2010 g37, can someone point me in the right direction on finding a thread/article on defoulers to avoid throwing codes.
Thx

 

Help! brand spark plug non-fouler: P/N 420002 and 420009

You drill one of them out with a 1/2" bit and then thread them together. Then you thread the non-fouler 'extension' into the pipe, and the stock O2 sensor in the other end.

 

Bump..

I did the non-fouler trick for my RTP's but its too long and smashes the o2 wires against the trans pan. It will ride but I hate the thought of it sitting like that. Anyone know the thread pitch or what size elbow I need to put a bend in the extender to point them sideways (parallel to the pipe)?

 

The extra O2 ports on my Test Pipes are M18x1.5
