I agree.Run NGK iridium 8s.
No worries after that.
BKR8EIX ?Run NGK iridium 8s.
No worries after that.
Thanks for that AlexTyndago has posted on this a few times, part nos for the NGK tipless race plugs. https://sites.google.com/site/tyndago/rb26dettsparkplugs
Its the Denso/HKS plugs that break. NGK's are fine.
I've got the BKR8EIX in mine currently - strictly they are ISO not JIS length so the contact in the coilpack may not reach down to the tops but you can just pull the spring out a little so it does.
I wonder if these are any good for street use. NGK writes that these are not to prefer on lower rpm, but these would suit perfect on a pure race engine, but they are overpriced.Yeah surface discharge type with out the electrode. I know regular ones work fine, even Denso ones should, but if you can go to the tipless plugs it is one less thing to worry about.

Yes I do but I noticed that even BCPR7ES did not work with 550 hp (flywheel) on my brothers R33 GT-R.Bolle, aren't you running 1000+bhp? BCPR9ES is WAY WAY to cold for a normal car.
BCPR6ES is fine upto around 450ish BCPR7ES (what I use @540) 500-800ish.
I get where you were coming from, I am working on something and I want to source the plugs in this picture (or at least rb fittment) my ignition is up to it but NGK's website is very time consuming, do you know any part numbers?Yeah surface discharge type with out the electrode. I know regular ones work fine, even Denso ones should, but if you can go to the tipless plugs it is one less thing to worry about.
