Hi all, first post in here, so thanks in advance for your help.

I've just brought some Splitfire coild packs for my Skyline R33 GTS (1993 L Reg).

It says I should install colder rated plugs (I've currently got DENSO PK16PR-P11 fitted).

Does anyone know if these are the correct type, or if not, could you advise me of what plugs I should fit, and what gap I should run?

Thanks again!

heat range 8, gap 0.8mm should do you fine.

if its the RB25det, then i think its BKR* where * = heat range '7', '8' etc, however, if you just changed the coils but your car is still std, shouldn't you still be using '6' ? and '7' if you're about 350bhp.
