I need the O2 sensor fouler since my Invidia testpipe went 72 miles before causing a CEL. The problem is that I have no idea where to buy one after going to Autozone and merely getting goofy looks when inquiring about the part. Any ideas?

 

They are called anti-foulers. You can get them at O'Reillys 18mm is what you need and they come in a pack of two.
Just drill out the center with a 1/2 drill bit. Works great.

 

Thank you for the suggestion. I went to an O'Reilly's, and still had no luck. If anyone knows of some place online I can get this purchased, that would be great. I have specifically stopped twice to get this fouler and have come up empty both times, I really do not want to go to a store a third time not end up with the part.

 

Call 918-798-9940 his name is Alex. He has the fouler in his possesion. I'm sure he would sell it to you and ship it for you. Tell him Gabe told you to call.

 

I've seen them in just about every autoparts store. i bought mine in o'reillys. Just go to there "Help" section and you'll see it. make sure u get the shorter 18mm one. theres no need to pay additional for someone to ship it to u.

This is what your looking for:


Part # : 42009

 

Maybe try AutoZone, Pep Boys, Advance or any automotive parts store.

 

anti-foulers, stack 2, shouldn't get a cel light.

 

Do I really need the set with the gasket? The set I got does not have that.
