the higher the number the colder the spark. i beleve the factory are bkre7's so i would imagine 9's

depends on which engine, 6 is the factory heat range for b18c (vtec) motors, so a 7 would be 1 heat range colder, but usually more then enough for most mods, even turbo/supercharged, until you start getting into really really rediculously high boost levels would you have to bump up to an 8 or a 9.

also, you can tell if your spark plugs are the right heat range just by pulling them after running the car real hard and evaluating how they look...i dropped to a 6 on mine (non vtec) and pulled the plugs and got a perfect result.



if your too hot, they will be melted, if your too cold, they will carbon foul real fast
