## Questions & Answers

**Q: Will these work on my 08 Tahoe? For some reason Amazon says they won’t**
A: They should work fine...this plug was factory installed in my 04 5.3 Tahoe and Amazon states it is wrong....

**Q: I ordered the 41-110 but the 41-114 is what arrived.  Do they work to replace the 41-110?**
A: No, the thread length isn't the same. What vehicle are these going into? If you entered the vehicle information, they may have sent the correct plugs for your vehicle.

**Q: Are they gapped?**
A: Specs get updated all the time. I have learned that the hard way recently. My '03 Escalade owners manual suggested Platinum AC Delco or NGK Spark plugs gapped at 0.060. When I received the NGK spark plugs they were set at 0.045 if I recall correctly. I went ahead and gapped them at 0.060 as suggested by the owners manual, I didn't noticed an improvement in acceleration or MPG. I have now learned that GM now recommends the Iridium spark plugs gapped at 0.040 for my SUV which is way different than what it originally came with.

***Notice: The spark plug gap is set during manufacturing and should not be changed or damage to the spark plug may result. Any new spark plug found to not be properly gapped should not be used. ***

**Q: these real or fake acdelco's?**
A: Real. Put them in my Silverado truck a year ago and they are doing a great job.
