R32 Gtr Spark Plugs

[DEATH]

So I've been searching this site and google for the past 4 hours - either my brain is fried (as it's almost 3am and all the threads I'm reading seem to contain people talking about RB20/RB25 GTST, GTT etc and mixing all the information and replies up) so can anyone tell me what the difference is between these model numbers?

I'm looking to replace my iridiums with some copper ones and from the list above what would suit a 1993 RB26DETT engine running 1.2 bar and splitfires?

Seeing as you have 7's there, I would say your going for the heat range 7. Lol

Just get bcpr7e

The BCPR and BKR plugs used over the various RB engines are very similar; one is an ISO standard the other a Japanese industry standard. Both are a resistor type plug and share a common tread width and pitch however the overall plug height differs; the RB20DE(T) & RB26DETT use a BCPR type the RB25DE(T) a BKR.

*The above is using NGK references

If you are looking to changing to a set of NGK copper cores to suit your R32 GTR (BCPR7ES) I can offer you a set for $29.04 + postage.

Thanks for the reply and information guys and yes I am going for heat range 7 Hadouken!

Picked up a set of BCPR7ES today from Autobahn for $29.94 ($4.99 each) - but thanks for the offer Kudos - I'll be hitting you guys up in the next few weeks though to get a few bits and bobs
