NGK TR7ix Spark Plug First Impressions

[Black02GT]

I run TR6iX, car seemed to like them better on E85 than the TR7iX. With the cooling of the ethanol and colder burn I prefer the 6s, on 93 I run 7s. They don't have the little piece on the ground strap if that's what you mean. They do have a VERY fine electrode but that's what let's you have the larger gap.
