What spark plugs for higher boost

Post by Martin F »

Car is going to the dyno in just over a week, I know this question has been asked many times but I am getting conflicting information, can someone in the know direct me to the plugs I should use for up to 1.9 bar of boost, muchos thanks :thumleft:

personally, I'd use NGK BCR8ES gapped to .75 - .8 mm, they're two grades colder than standard and around £3 each from any motor factors

What are the difference between those you have mentioned against the standard plugs but colder, ie. NGK BKR8E.

Also I presume iridium etc. aren't going to help me in any way, cheers for the advice Rob :thumleft:

in real world terms, nothing. one is slightly longer than the other (not the part that goes into the engine) but both are totally suitable
