O2 sensor spacers

I have just learned about a new solution for that pesky cel light. The gang a Svc recommended a o2 sensor spacer when you have issues with the cel due to long tube headers and high flow cats. For the price I've Seen they are a cheap remedy for the problem, and pass a emissions inspection. I was wondering if anyone has used these with success?

I saw that mentioned as well and was also curious.

You still having problems? There like $14. Sounds like a cheap fix!!!

I have used them. I put the stock tune back the spacers and new o2 sensor to pass emissions. Took them off and put my old o2 in so they don't get weathered. I'll do it again at next emission test.

many of used this method with success. there are some good write ups online too. the key is 2 get 2 sets of the antifoulers(spacers). drill 2 out large enough for the o2 sensor to fit thru. thats what the 02 will screw in, then screw that into the undrilled antifouler. then screw that into the ****.

I don't quite understand nick. There not sold ready to install?

no u take a spark plug anti-fouler and modify it to work.

there are o2 spacers out there already made but they are expensive for what they are.

For $50, it's not that bad, if you want to keep the rear O2s on in a custom Tune.
Good way to help keep the motor safe. IHMO

It sounds like SVC would recommend that after reading their posts.

Casper electronics sold a plug in simulator for this. It eliminated the rear or all together

I don't think Simulators will work on the new 2010 1/2 and up PCMs.

The rear O2 are monitored quite differently.

But please prove me wrong for everyone's benefit.

The one that NickPic83 put up looks intriguing!
