I happen to know a guy who has 2 of these non foulers he's not using on his '98 parts truck....pm me if you want.....

 

I did find a possible solution. Apparently some motorcycles use the 12mm o2 sensor. There is a company that makes a 12mm to 18mm adapter.



Then you use these 18mm to 12mm reducer to fit your o2 sensor in the adapter.

 

Hello Good People,

Looks like another helpful thread that I have arrived to a bit late.
For those that are using this non-fouler/spacer are you still having good results with removing the P0430?
I replaced my entire exhaust system a couple years ago and just recently got the P0430 error.

New spark plugs. As for the plug wires they have less than 2000 miles on them.

I have heard of people using non-fouler/spacer for spark plugs, but no feedback on the success of using with 02 sensors.

Thanks

 

I used them on the downstream O2 sensors on a Dakota I used to have. They seemed to work well. I got a code for them once or twice a year. The code is easy to clear.
