i was running the ik24 which are a bit cold for naturally aspiration, im turbo so thats no matter, but they are about 100.00 for 4 and i couldnt really notice a difference from when i switch from the ik24 to the ngk 7e's...you would need to dyno to actually see if you are gaining any power.
and the only way you would really gain any power is it you were turbo, went with a colder plug, had a ingition system where you could open the gap larger...then you could see a real gain from spark plugs..but not just by getting better plugs
