Well i have 500+ miles on them now which is very impressive because my cel lights (po420,430) with the dynatech headers would come on after a cel clearing every 75 miles or less. I was a non-believer but took Gremlinsteve's advice and a couple of others and took the plunge. Even if they only work every 500 miles for me that is gold because i will be able to pass emissions here in H-town.
I used the autozone spark plug antifoulers 18mm and used 2 per side(stacked) on the rear 02's only. They are in the help section and i beleive the part number is 42009. I used a 1/2 inch drill bit to drill the inside all the way out and installed. Will keep ya'll posted with mileage.

Okay, at first I thought that you were using them on the spark plugs, whew.
Got me all excited....................LOL

Have owned my share of 12 & 13 second cars, am happy now with my stock RT.
Ya, I got my fingers crossed right along with ya Mike - and I don't even have LT's. I've put almost 300 all-around miles after installing my second set of anti-foulers too. This is the longest I've gone CEL-free since I installed the MagnaFlow high flow cats... I know I'm not out of the woods yet, and I may very well see another CEL at any time, but I figure at least I've affected it, and it looks like I'm going in the right direction...
So.... what exactly is it doing to prevent the CEL? I'm not clear at all on this...
Still in love with my first wife, and first car ('68 Charger)... Still have the wife!
It basically moves the 02 sensors out of the direct line of exhaust flow. With hi-flo cats/headers the exhaust flows much greater. CPU thinks there is too little of a discrepancy between the front and rear 02 sensors and throws a CEL. Thus they don't get all the blast comming out of the hi-flo cats and keeps the cpu happy. Some people say only 1 fowler works. I started with 2 and so far so good. May have to put three. There are also people who have used them to no avail. Kind of a hit or miss thing.
I will have to try this as well since I made it 40 miles before the CEL came on.....lol.The Kooks already have a tube that moves the 02 sensor 2" out of the stream......Meister said he used 2 antifoulers on his and the cel went away.Keeping my fingers crossed.

All im looking for is a way to pass emissions. Last time i got lucky by clearing the cel with my superchips but the car didn't have enough trips on her to read . I put 75 miles on her and took her back and the car still wasn't ready but the chick gave me a break and passed me. Here you only get 2 shots at it and if the gal hadn't let her pass i woulda had to get the sticker some other way. Woulda cost a little more dough tho!!!
If these things work just enough to show me as ready.. than im happy..
oh man. When you said "anti-fowlers" I was thinking of something else.
don't mind me. One of those days.

I have several thousand miles now without a CEL for rear O2 sensors due to the anti-fowlers. They work!
