AKA Defouler.

There's a couple guys that sell them on ClubRSX for pretty cheap.

You can make them yourself for about $4.

1. Buy a pack of Help! 42009 Spark Plug Non-foulers.


2. Drill out the middle hole on one of the non-foulers with a 1/2" drill bit.

3. Screw your secondary o2 sensor into the top of that drilled out non-fouler and it should fit in there almost perfectly.

4. Now take that non-fouler/o2 combo and screw it into the top of the UNMODIFIED non-fouler.

5. Screw the whole thing into the second o2 bung on the RH and plug the o2 sensor back in and you're done.

It will look like this when you're done:


o2 Sensor = Drilled out non-fouler = unmoddified non-fouler = RH
