Only $10 shipped from eBay. Will they fit my car? And should I buy them used? They are just so cheap compared to new ones.

They're 1 step cold from stock, and I would stick with the stock heat for N/A. IF you're thinking for boost I think they're still too warm.

You would have to ask him what engine he had them on. If he had them on a SOHC, they would be perfect for a DOHC since SOHC's use 1 step hotter than the DOHC. If they are from a DOHC, I wouldn't buy them. Saturn did a good job of picking the stock heat range.

What is this whole heat rating thing? I tried a search for it, but couldn't find anything.

What do you mean by boost? All I have now is a WAI, and I don't plan on getting a turbo if that is what you mean.

He's got a SOHC.

Don't get the plugs. You aren't running boost.

Crap, I didn't even look at what he had.

Yeah, if these are 1 step colder for the DOHC, and you have a SOHC, then these would be 2 steps colder, which is only for boost applications.

Want info on what plug heat ranges mean? Here you go.

This is a good one:

Ok, cool.

Now how do I know which kind to get? On NGK's site, the only plugs it showed that I could use were stock plugs.
