## Questions & Answers

**Q: Is this the oem factory spark plug to fit my 2014 honda crf 250l dual sport motorcycle?**
A: It was the oem plug for my cbr250r which has the same motor. Doubt they take different plugs but it's possible.

**Q: What is socket size of the ngk simr8a9 plug?**
A: It is 5/8 or 16mm.

**Q: Is this plug pre-gapped ?**
A: Yes.  From what I have read about iridium plugs is that you should not attempt to gap.  As G said, check it incase it was dropped.  NGK puts a thick cardbord sleeve on the electrode end of plug that should prevent drop damage.
