BKR7EIX (0.8mm gap) or BCPR7EIX (0.8mm gap)

mrtwo · May 15, 2005

Hello all, getting stressed now and have tried everything to get a definite answer out of the search function. I have a r33 gtst spec 1 with uprated turbo elbow, downpipe, de cat, exhaust and filter running standard boost. Can someone please tell me which one of these two plugs BKR7EIX (0.8mm gap) or BCPR7EIX (0.8mm gap) I should be using. Any help would be much appreciated.

Thanks Ade

I've got no idea but have you tried asking whoever supplies them what the difference is?

The faq is not working on sparkplugs website and from using the search function on here it would seem they don't always give you the correct info. I thought I would try and get a definite answer off the experts on here

Anyone?

BKR7EIX are ISO standard plugs, BCPR7EIX are BCP/JIS (Japanese Industry Standard) type plugs. As you can see from the diagram ISO plugs are 2.5mm shorter than the Japanese type. I use BCPR7EIX type plugs in my GTS-T with no problems, so I would go with them.
