Very curious as to what fellow foxers are using for plugs? I've always used autolite copper plugs and now that the new engine has aluminum heads, I'm not so sure...
Right now it's got the autolites, but I'm told to use NGK V Power. I once tried the V powers in my old 302 that sported GT40 iron heads, and a complete aftermarket ignition. I lost most of the plugs on the freeway. Car began misfiring like mad, I pulled over to find 7 of 8 NGK's had shattered porcelain
Quit using that brand since...
What do you guys have good luck with ?

That's what I'm hearing from the locals... NGK is the way to go..
maybe I just got a set that had been abused in shipping or something and didn't notice hairline cracks....

I run whatever copper plugs were recommended by Trick Flow in my Twisted Wedges. Autolites I think, but I don't remember the number.

Prior to that, I ran Autolite Iridium plugs in the stock heads. Those plugs are more expensive, but I like the fact that you never have to re-gap them, and they will basically outlast your engine. I actually still have those plugs sitting on my shelf. They don't fit in the TW heads, otherwise I might have used them. They're still in perfectly good shape.

I run Autolites in pretty much everything. Woody even recommended them for my new engine.

Autolite 25's "Side Gapped" (I've noticed a slight difference in response and the 20+ MPG on highway is nice too!"


Although, I am also running an MSD Coil, and 6al box

OEM motor craft copper plugs.

I have NGK in my G35 because those are the OeM plugs. NGKs are pretty good plugs though.

I like to stick with copper plugs. NGK doesnt actually make a copper plug. I've always had the best luck with Autolite's in the stang. I am not dissing NGK, I will agree that NGK is probably the best all around plug for any type of engine, i've used them before in the stang and didnt notice a difference from the Autolites. I tried motorcraft one time and it just didnt seem to run the same but I cant exactly say it was because of the plugs, but that was a while ago. I run factory motorcraft plugs in my ranger though.

I think if you had 7 out of 8 porcelains cracked or shattered on the plugs, that it just might have been an install problem, you would have noticed cracked and shattered porcelain when you gapped and held the spark plugs. It's easy to crack a plug if you don't have the socket on perfectly straight when tightening the plugs down. I run ngk v gapped at .040 - .044 never had a problem yet.

I usually run the copper Motorcraft plugs, but recently bought Champion copper plugs cause that's all they had at fleet farm.

I could be wrong to but when it comes to the ngk's don't you have to use a resistor type plug otherwise you could encounter ecu/electrical issues? I know some ngk's are and some aren't
