Default Delco

They're good enough for GM, they last, they're not expensive to replace - What's not to like?

Make sure the plugs you get last a long time, as you don't really want to revisit this job. The original factory plugs in my car went over 100K and were still looking good when I fnally replaced them.

I've used the bosch +4's in my car for over 100,000+ miles with no problems.
