How long will these plugs last?
Just picked up a set of NGK TR55s. Where should I gap them and how long before I have to change them again under normal driving, occassional track? Thank in advance.

Re: How long will these plugs last? (tslawsky)
I just installed mine today. The box says they should last around 30K miles. The recomended gap for an LS1 is between .060 and .055 I've been told the gap tends to get bigger after some miles are put on so most recomend them on the tight side :cheers: BTW I'm very happy with them. The car runs a lot smoother
