Great for jrsc, or ctsc
I bought these since i needed one step colder plugs, and these have lived up to the abuse. I don't daily drive my car, but i go on road trips and never had a problem with them. I always used NGK, or Pulstar, but thought I would give Denso a try, plus IK24 just sounds bad to IMO :-P

These were easy to install and I've had no problems with them since. I have these on my supercharged RSX that I drive daily and would buy these again.

Worth the loot!!
I replaced my spark plugs at 92,000 miles. Seems to run quite smoother, and start up easier than the worn plugs. Other than that, no complaints :)

Great plugs, Great quality!
Hold the NGK next to the Denso's, the NGK just feels cheap. I used NGK all the time and dont find a problem with it. I used Denso's when i first boosted and it seemed as if they were more durable. But i have no scientific proof on this. Both are good plugs, if u have the money spend on Denso's.

I received this product and Club RSX is quick with sending product. Once I received it I installed it and may I say that my S2K is spitting a lot better... Way better response, I think I might stick to these Denso's from now on.
