Spark plugs?

[s12reamer]

I need to know which code of plugs to put in the silvia, I would like to put in the BKR7RES?!?! (the slightly colder ones) but are these only used on modded s12's? If so I'll go with the standard book listing for now which was something like 6-11 blah blah.
Your help is most appreciated

Standard fit is BCPR6ES

Cold type which is preferred for increased boost is BCPR7ES

Mental boost people would want BCR8ES

Ok thats great I thought as much so picked up the standard ones. Do you know what I should gap them too?

Thanks

Why std plugs are you not looking to tune it??

Spacing on the colder plugs should be set at 0.9mm.

I shall tune it (actually it flamed the other day which gave me the impression it was or at least overfuelling a little). I just want to get it running alright then i'll add the intercooler. I'll know in about 2 weeks whether i'll do it up or not Ive just gotta see what other problems arise.

As Adam suggest .9mm.

If it was standard then 1 to 1.1mm.

thanks for the reply.

Im about to do these plugs tonight along with oil, wiper blade, fuel filter & maybe coolant.

Out of interested do you think this car has been abused? everything points to it being that way but it still runs I guess.

Rear drivers side brake caliper - needs replacing
Gearbox leaking
Right rear bush worn

Maybe its just me imagining it, still cant believe I picked this beauty up for £70

So if it hasnt been abused its about to be hehe, bring on the drifting!
