## Questions & Answers

**Q: Are these plugs pre-gapped ?**
A: They should be. THOUGH, and I stress, it wouldn't hurt to check them prior to installing them. I've purchased pre-gapped plugs before and they were off just a bit. 39 vs 44 as an example.

**Q: What is the expected milage for these?**
A: 40-50k miles (more expensive OE 9029 are rated 80-100k miles).  Ref. ngksparkplugsdotcom

**Q: Are these 5/8 spark plugs?**
A: These sparkplugs  are 14mm or 9/16. Socket fits snug with either one you wish to go with . Strongly suggest the magnetic spark plug socket .

**Q: Will this fit a 2015 Nissan rouge sv?**
A: Amazon site should tell if they fit.
