Got my iridium spark plugs on Saturday (thanks Mingster)

I know I said that I would go to the dyno but couldn't resist installing them, sorry.

The results: I don't know about power but I can tell you that the car idles much better and the hesitation starting and when coming to a stop is gone.

I also have the adjustable FPR and the issue with the car taking longer to start is also somewhat better with these spark plugs. It starts faster.

Didn't calibrate them as I remember someone saying that you have to use a smaller gap and they come factory calibrated. My IK24 came with a .08mm gap while the minimum for the stock plugs is .1mm according to service manual.

I also installed a set in a turbo Miata and the car exhibits better throttle response and the exhaust temp is about 150 deg. celcius lower at WOT. That's pretty good for a spark plug swap.

Can someone verify the gap thing? Mingster?

Pepe,
you got IK24's? I got IK22's from Mingsters group buy.... what is the difference... Helms book says PK22 as replacement... just wondering...
I havent checked the gap on mine yet, but I heard someone say not to gap these plugs

Installed them today. No bog or hesitation from idle when starting to move, compared to fresh stock plugs. Engine runs smoothly, idle may or may not be smoother, but was essentially steady before. These plugs are fine by me!
