Have any of you used these? I didn't know they existed until I looked on Auto Zone's web page. I called them and they said you screw it in the head and then screw the spark plug into the non-fouler. Of course they said it worked good. But I would like an unbiased opinion from someone who's used them or knows someone who has. Thanks.

 

I've never used them, and I don't know anyone who has, but I've heard they're not a real good idea because they go around the spark plug and restrict the spark (or something like that). The only reason you would use them is if you had a really bad oil leak that was fouling the sparkies.

Don't even think of using one. They screw into your spark plug hole then the plug threads into them. They space the plug out about 1/4" or so. I'm not sure why they try and hawk junk like that sometimes. I don't know anyone that has used them because my friends know better.

They will work to the extent of not having to replace your plugs as often from oil fouling.

I used to run them in an old ranch truck we had, but performance was never a consideration, just the hassle of pulling and cleaning the plugs every weekend.

With the anti-foulers in, I never had to pull them again.

Keep in mind this truck only saw highway speeds occasionally, and was mainly used for putting around pulling things and carrying things.

I'd say if you're blowing a lot of oil, and with the PIA it is to change plugs in these cars, they'd be worth a shot.

 

I would try hotter plugs and a little more plug gap before going to a item like that.

I'm using R45TS gapped at .035. What would a hotter plug be? wouldn't a hotter plug make knocking more likely?

 

An R46 with 45 gap would be worth a try. The R46 isn't a big enough change to cause pre-ignition.
