## Questions & Answers

**Q: Is this a 12 mm or 14 mm spark plug I need this information for the gapping tool**
A: Neither!! 
You need to gap them properly yourself, so get a “gapping tool” if you plan to use them properly.

They take a little work, but they are OUTSTANDING! I have them in my Stage 2 GTI that makes damn near 350hp from a 4 cylinder...

They do the job! Just use them with care! 
#NotForTheLevelOneTech

**Q: are these pre gapped at.44?**
A: Can't remember the gap mine came at but as a general rule you should never trust the factory gapping. Get the electrode bender and the shim set for about 4 dollars to check/set the gap yourself. Do not! Use a gapping disc on these plugs, you will damage the iridium tip.

**Q: Does anyone know the difference between the ikh24 and the ik24?**
A: From what I can tell they are completely different plugs.

**Q: Does this fit an 01 Tacoma ?**
A: Yes, but I wouldn't recommend it. This spark plug has a very tight gap and isn't optimized for your Tacoma.
