Hey guys,

A mate from another car forum has some old NGK BKR5EIX-11 Plugs for sale (They have done 5000k) they are gapped at 1.1mm, would that be fine for standard boost (well about 9-10psi with exhaust mods/intake)

Would they be ok? or should I steer clear? (he's selling them for $40 for all 6)

y not just buy new??

i would steer clear coz it ur cars running a little to rich it will kill them

better off going for a race plug for around 8 bucks each

the number off the ngk race plugs are R5672a-8

8 being the temp rating and i have my rb20 running on 13 psi with 35000 gap

works a treat 10 psi maybe use a 7 heat rateing

hope it helps

They are the standard plugs for the RB25DET. They should be fine in yours.
