Good price, first drive went well.
All but 2 plugs came at .028 gap. Just installed in my supercharged c5 (after gapping a little tighter) and upon first test drive all seems to be well. Only time will tell but as of now I give 5 stars.

If you need a plug for your power adder car or truck.
If you need a plug that's good quality and a few steps colder than stock this is it.
