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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***. on 28 February 2026* Excelentes bujias las mejores que he probado ### ⭐⭐⭐⭐⭐ Review *by A***R on 23 March 2024* les bougies sont excellentes mais diodes n ont recu ### ⭐⭐⭐⭐⭐ Review *by A***N on 23 February 2026* Good quality NGK spark plugs, immediately brought back the snappiness to 2.5 Altima.
