I bought haro'* 00 ssei coils & ICM the other week and I finally got a chance to swap the coils in. It idles a tiny bit smoother, and the midrange seemed to have a little more power.
Nothing huge but it was noticeable.
IMO it was worth the $55 bucks I paid.

I was 5 dollars short :(

have you tested them for resistance....and how do the compare to the ones that were on the car?

I lost my multimeter so i didn't do the terminal test.
I was driving around more and my midrange definitely feels smoother.

That'* the same thing I noticed when I switched from Stock coils to MSD'*. (I had one bad coil, but had borrowed one from Jseabert until my MSD'* came in).

So I upgraded from the same coil you had stock, to another coil slightly hotter than what you just put in. I was pleased as well. Smoother idle, and a slightly snappier midrange.
