    spark plugs

    i'm getting all the bits n bobs i need for my cars 1st uk service in 3years
    ( the guy i got it off only did 3000 mile in 3 years )

    i'm sorting out plugs, now i was going to get denso 1k20's but as i can get a good deal on some stuff,
    i can get HKS plugs ( that i'm told are denso anyway )

    what rating HKS plug do i need ?
    they are heat rated 6 / 7 / 8

    i'm guessing as i dont intend on much engine tuning i'll be ok with heat rating 6 or 7 maybe ?

    Come on guys help a girl in need

    I'm going to change my plugs to.
    I'll upp the boost to 0.8bar with full 3" exhaust, pod, FMIC and yaddeliyada. Is it 8's for me?

    7s will be fine until you go over 1 bar.

    Let's put it this way: none of the Euro drivers with JDM S15s should need to use 8s until they've had their ECUs remapped - track or no track. Colder sparks aren't going to stop your engine detting.
