## Questions & Answers

**Q: Will these work on a 2004 chevy tahoe lt 5.3l?**
A: Yes they will with the right fitment for your vehicle. They work just as well as and even better than O.E. AC Delcos. They've shown me to burn clean and save fuel. Try them out and you'll see.

**Q: Does it work for my 2011 Chevrolet Express 2500 4.8L?**
A: Yes.

**Q: Well it fit a 2015 camaro v6 ?**
A: I don't know. My advice to you is to pull a plug out to be sure and replace with the same plug parts number. Your car engine was designed to use that type of plug. ( size and heat range) Good luck Patrick D

**Q: Are these in the original boxes?**
A: YES in our origianl boxes.
