I checked the ngk site and they are 0.9.

I've checked alot of places and I can't seem to find BCPR6ES spark plugs with 0.8mm gap I can only find 1.1mm and super cheap say (after rego checko) they are not a right fit for the rb25. After alot of searching and doing my head in I found BCPR6ES with a 0.9mm gap from justjap so that's what I went with... ?‍♂️ Stock rb25
