Spark Plugs.. ??

[Raceof]

So I got a set of DPR9EIX-9 for my XB12S... will these work ?

Also a 5/8 doesn't fit very well but an 18 mm sure does.. what gives ?

Here they say its just the Hex size and something about not having a cap that makes them different

NGK-DCPR9EIX those or the 8's. The 8's are practically stock and the 9's have a better heat resistance. And for your socket, is it an actual spark plug socket or just a regular socket?

Also make sure to gap them to 0.035, which the 8's are already gapped.

My 9's have always been gapped - I check them at counter before buying.

The dcpr9eix plugs i bought were under .030 so i had to gap them. i would have ask for a different set but they had to special order them. Orielly's got them for me for just over 6$
