Might be the first thread but my O2 sensor on my test pipe went bad, replaced it with a universal one but now the tip is too wide and long so now it won't even let me screw it into the spark plug foul. It's touching the inner part of the spark plug foul, what can I do? Do they make them spark plug foul longer or am I fawked? Any help would be appreciated, thanks...

 

I wonder if you can add a third one?
Could you get a S2000 O2 sensor instead of the universal one?

 

I could pick up a OEM O2 sensor instead but the price they wanted was $250 or so, universal one was only $70ish. I know, you get what you paid for but it's too late now cuz I'd already got it, only thing I could do now is try to get the sucker on.
Someone else beside me gotta have gone through this problem, if not then lets make this a good thread for the next guy who will and is looking for answers as well.
Btw, the S is on jackstand or garaged 'til I can figure this out so please Help?

 

Drill out the anti-fouler more/further. Is it touching because its too wide? Too long? Both? If need be add a 3rd anti-fouler and drill the first two wider. I have 4 sitting here at my house actually, anyone feel free to hit me up and I'll send them to you if you pay postage and the cost of the envelope.

 

Sup S2kracka, I'd drilled it but it's still way too small. I'd customized the O2 sensor and it fits perfect now but the CEL is still on even after I'd resetted it. Afterward I'd thought to myself that maybe I'd replaced the wrong one, bought another one and replaced the O2 on the header as well, resetted it again but still that damn CEL came back on. At this point I'm cluest, gotta take it back to Auto Zone so they can hook up that OBDII on it again and see if it's the same issue. You think maybe I need 3 anti-fouler? It's worth a try, I'm open for any other suggestions now.

 

Did some searching on ebay and here what I'd found, I should of gotten something like this instead of the two in one version.
