## Questions & Answers

**Q: r the lugs pre-gapped**
A: Yeah, mine were. But I adjusted the gap to the spec. Plus with shipping you never know if the gap gets changed or not. Get yourself a sparkplug gap tool.

**Q: Can a AP 104 misfire in two weeks?**
A: I suppose it is possible, if it is defective, but a normal plug should last for years.  I recently installed APP 104's in a Taurus Duratec DOHV, and the car developed a mis-fire on Cylinder 3 within a couple of weeks.  Then, a few days later, it developed a mis-fire on cylinder one.  As it turned out, the problem was not the plugs, but the COP coils.  I'm not sure why they both decided to die within a short period of time after I replaced the plugs, unless jostling the COP's in removal and installation somehow damaged the internal electronics.  The car was 14years old and had over 200,000 miles at the time.

**Q: Is this per plug or per package of 4**
A: Hi!This is for 1 Spark Plug.

**Q: Is this 1 spark plug or 1 pack? I'm needing 4.. Thank you in advance!**
A: Just 1!!!
