Spark plug non foulers...

"You drill out the anti fouler, and then just screw the o2 sensor into it, and then it into the o2 bung."

I drilled out one of them but used both of them. I have not had a cel in over 1000 miles. So it works. Before I did this I got a cel within 50 miles.

Agreed. You drill out the fouler that the O2 plugs into, then screw that into the second fouler. Then screw it all into the bung. I've been around 10k miles now that way with CEL.

ok so you say drill 1 and blkzoomzoom says drill both??? which is it? lol
 
i drilled them both out. But it was a tight fit using a 1/2 inch. I had to grind it down some after that and it barely fit. Looks like no air can get to the sensor? Is this right. I drove 50 miles so far with no cel? Before it came on in 10.
 
the 2nd one i only drilled a little. I figured the sensor would need to see a slight bit of emissions in order to know the sensor works. That way it won't throw a cel saying the sensor is bad?? Just a hypothesis. I have gotten no cell in 200 miles.

I just did the mod yesterday morn, and drove ruffly 150 miles and no MIL/CEL (I did drill both to 1/2 inch,everything fit smoothly.)
 
I drilled both about 6k. ago...I still had the hi-flo cat but I got a check engine light anyways before the anti-foulers.

Since I put them in (6k miles) I haven't had a check engine light for this.
