I went to the parts store yesterday and was going to purchase some NGK 55. I know there are four types of this spark plug but does it matter which ones I purchase. The store only carries the V power ones. I am installing my headers so which plugs would work. thanks guys

Do these come pre-gapped or do you have to gap them to .050?

Thanks

Always check the gap on any plugs you buy. Checked their site and they say stock gaps are .060 for 2001, .050 for 2000 for the same plug...don't know why???? I've always gapped mine at .055.

TR55 are for naturally aspirated cars and TR6 are for turbo nitrous and supercharger cars
