I was thinking of changing my plugs to Iridiums. I know there are IK22 and IK24(step colder). Was wondering if I was wasting my time to put them in. If you use them, did you go with 22s or 24s and why?

thanks!

Just picked up a set of IK22's. Let you know next week. I decided not to go with the one step colder, because I dont plan to have forced induction on my car in the near future.

P.S. Can you PM me your number Id like to pick up the oil if you will be around SF tomorrow.

You COULD go a range colder but

I went to IK24s because of the SC. Subjectively, I can't tell the difference except that I got to look at my old plugs which looked like I was running lean.

Objectively... well I have no objective data since I haven't been on a dyno after the plugs.

If you are NA and don't go to trackdays, stick with IK22.

If you NA or SC and drive hard on the streets, go with IK24

If your NA,SC, and Track your car, use IK27's.


I use IK22 for street usage and swap to IK27 for trackdays. Just make sure you swap out the IK27 after your session or else you'll foul the plug within couple hundred miles.

i threw in IK22's... been runnin them for a couple months.. no problems... no comments... dont think its a waste of money tho.. they weren't that much more than regular ngk's that i used to get

Got them in the mail yesterday gapping them was kinda a PITA. They all came gapped too small. Way under .4 to sparkplugs.com they have fast service if anyone wants them
