Alright so I was searching around about spark plugs and came across some information regarding the IK22 and IK24. The 22 evidently is stock heat range and the 24 is 1 step colder. Some were saying that N/A felt better with the IK24s.

Some were also talking about N/A feeling more powerful with a smaller gap around 35ish as oppose to 44ish which some disagreed. Any input on these ideas?

Also was wondering if 1 step hotter would be better if running water meth? Or would 1 step colder?

 

i could not tell a diff from stock plugs and the 24's. mine are gapped at 38. Are you N/A? Run a hotter plug with meth, all its doing is essentially cooling the combustion process and boosting your octane.

 

The heat range is just to prevent detonation and plug fouling. If it's too hot the ceramic will get too hot and become an ignition source. Too cold and the plug will not be able to clean itself and foul out. The gap is a balance of being small enough to keep from blowing the spark out, while being large enough to present enough spark to the mixture. Plugs do not add power if selected properly. They only remove power if selected poorly.
