o2 sensor defouler / spark plug defouler

Does anyone knows if these are sold locally?

Basically it places the o2 sensor further away from the flow of the exhaust, so as to prevent it from throwing CEL code.

i'm sure you could just get a fitting from pirtek that did the same thing

where can i buy it?? are they all the same size?

actually you do know that if its too far away it defeats the purpose of the o2sensor

Yes, but all the secondary O2 sensor does is to warn if the cat efficiency has fallen below the cutoff point. It doesn't measure A/F ratio. That is carried out by the primary O2 sensor.

that is for newer cars like euro/ dc5r?

dc2r only has 1 o2 sensor

Then the DC2R's sensor is before the cat, and if it throws a code, you should read the code to see what the problem is, rather than to get a defouler.

yes code is o2 sensor

yes code is o2 sensor

That means your O2 sensor is faulty. It is not caused by your exhaust being too rich. The single O2 sensor on your DC2R is supposed to read Rich/Lean. On newer OBDII cars, there are 2 O2 sensors, the 2nd one is meant to check if the cat is failing. So for OBDII, you can use a defouler on the 2nd O2 sensor to avoid CEL when you use a high flow cat. But there is no point putting a defouler on the 1st sensor because it reads rich/lean instead of cat pass/fail.
