I'm looking for a set of replacement spark plugs and I'm wanting to put either copper or iridium plugs on it. I've heard that Iridiums are the best to get for neons? I was looking on autozone and I came across these. Has anyone had experience with these? How do they fare? They say that they're "better than spark plugs"....if they're not spark plugs, what the @#$% are they?

 

Coppers work fine. Save your money.

 

If you want a bigger spark kernel, side gap your copper plugs. It's free to do if you have a Dremel and doesn't take a lot of time.

 

It's not really that important. I was just wondering, and I don't feel like doing considerable damage to my plugs. :P

 

Side gapping works as long as you take the time to do it correctly.
