## Questions & Answers

**Q: Do i need anti-seize lubricant with these spark plugs?**
A: You definitely should use antiseize. Anyone who tells you different doesn't know what they're talking about. GM tech for 20 years, and I never installed a spark plug without antiseize, ever! It's even more crucial in an aluminum head.

**Q: Will these work for 2014 chevy silverado ltz 5.3?**
A: I have a 2014 5.3 LT and they fit my silverado. Check with a local parts store if your not sure.I bought a replacement plug at sanels.

**Q: Conflicting reviews, are these pre-gapped or not?**
A: They are pre-gapped

**Q: Will this work on a 2007 Chevy avalanche**
