## Questions & Answers

**Q: Would this fit in my 1995 chevy k1500 amd what should be the gap ?**
A: They should fix if it's a 5.7 l(350). The gap should be 35. Look on the sticker under the hood(either on the air cleaner or the front support on the radiator)for the gap just to make sure.

**Q: what is the best plug recommendation for my 1992 ford f250 460**
A: Hi,

These spark plugs will work for your 1992 Ford F250 7.5L 460

Thank you,
B&G AUTO PARTS

**Q: What's the thread size of the plugs**
A: 14mm

**Q: Will this fit a 1987 350 in a k1500**
A: Yes, but I would recommend E3s instead—I use these in my 350–more spark and power—most of all better gas mileage
