Looking to get a spacer for my stock O2 sensor so my check engine light stops coming on with my HKS exhaust. Anyone know where I can get one? AMS is a no go.

 

This is how to make a mechanical o2 fix if you have a test pipe/resonator/high flow cat, that gives a cel. You can find it on ebay for about 15 dollars shipped. But why buy it when you can make it for 3 dollars using parts from your local Pep Boys?

First of all you will need 2 spark plug anti-foulers (18mm). It is made by the HELP! brand part#42002 or 42009.

You will also need a 1/2" drill bit and drill. Or a drill bit close to that size

Drill one one the anti-foulers so that the o2 sensor can fit. I recommend using a vise grip and lube for the drill bit if you ever plan on using it again.

If it doesn't come out nice use a dremel or a file.

Put the one anti-fouler you drilled and connect it on top of the one you didn't. Now you don't have to buy a electrical fix and splice your wires.





Dont you just love evoM??? 4 minutes and you have an answer with part numbers and where to get them.

 

Yes, thank you very much! My next question I'm sure has been answered, I just can't find it. What is it that kicks this light on and why?

 

First off, did you have the code pulled ???
If you haven't, the you are assuming it's because of your exhaust (and it might be ) but you won't know for sure until
you know what code # it is. You have have anoter more serious problem - overboosting, lean condition.
I didn't get any codes because of my HKS exhaust alone. I only started getting a code after changing to a high flow cat.

You can usually go to any auto parts store, and they will pull the code for free. Here where I am , we go to Autozone.

All that said, if the code is a P0420 (cat efficiency) code, then it happens because the readings from the front O2 and
the rear O2 are too similar; the cat isn't doing it's job as it should be in reducing emissions.

 

Sure did . Maybe I should have been a bit more clear. I put my Helix downpipe, test pipe, and HKS exhaust on all at the same time. Didn't mean to imply that the cat back was the reason for the code.

 

Or go here, spend $13.99 with free shipping, and you don't have to use any tools or rig something up.

Good find! But like my dad says, "I have more tools and time than money"

 

Hmm wow. You have to buy 2 anti-foulers anyway and then do the work. $13.99 is pocket change and you don't even have to leave your computer.

 

Getting up and doing stuff is a welcome change. I sit at a computer allllll dayyyyy loooong.
