TR55's unless your going with Nitrous or FI...then TR6's....

[2001NBMZ28]

The NGK stock number for TR55's is 3951 - just in case the person behind the counter doesn't know what you're talking about.

Auto light 103 are just as good as the ngk and the cheaper and last longer unless your going to spray go with the ngk's. :yup:

and the auto lights are a Ford product, now why would I want to put a Ford product on my GM car?
