Does anybody have any experience with the E3 or NGK Iridium spark plugs? I'm just wondering which would be better.... Also, since you cannot gap the E3 plugs, will that matter for the Mustang which calls for a .052-.056 spark plug gap?

Yes, the gap should match stock specs. Get copper plugs from the auto parts store.

Spending money on expensive plugs gives you no performance gains despite what their sales/marketing department tells you.

This is true, electricity finds its shortest path and wont create more than one spark so kinda defeats the point of e3 plugs. Also iridium are only long life plugs and that's all, its just a coating and wont create any kind of stronger spark. Copper conducts best and last plenty long enough.

I forgot to say I am a fan of ngk v power spark plugs, I have noticed a difference in every vehicle I've put them in

i had some iridium's and did not run right it would bog, after i went to the auto parts store they said they were too hot for the car.

e3's are to the newbies of today what ****fire and crapid fire plugs were to me in the late 80's/ early 90's , the latest and greatest BS!!

Ok so I went back to the auto parts store, and I got some NGK V-Power Spark Plugs. I'll put them in tomorrow and see how they do. Has anybody else had much experience with these plugs?
