non foul spark plug
 

i went to auto zone to see if they had them for mine disco o2 senor but they didnt have the right size... i want to know if ya know what is the part number or what size i need.... thanks

I have no idea, did you take your old O2 in to match it up?

yes sir and really no luck but i pick up couple and try them out

That sucks, wish I could help more.
Once you figure it out post it please.

oh i will and i will take pics on how to do it for sure....

Good, when my cats go I'm doing this.
Until then, if it ain't broke I ain't fixin' it.

after 12 hrs of refab the exhaust system minus the cats with the non foulers in place, i had the old codes clear out about a wk and NO CODES SO FAR so the non fouler does work BUT IT MITE ACT DIFFERNT ON OTHER DISCO 1....

they dont make the right size non foul spark plug for our o2 sensor ,so i went with the 42002 ones so i had to grinded the tips off the non fouls and weld both of them together to make it longer then i drill out the center of non fouls so the o2 can sit in it then i WELDED o2 sensor to the non fouler then WELDED IT to the hole

DOWNFALL, if ever they ever go out.... it will be pain in butt to grinding them off and what not but so far i like it

Very nice.

wow 50 bucks for thems when you can get the non fouler for 7 bucks but if you cant find a welder then that whould be the best route....
