Spark plug gap size?
Hi folks,
So I searched around prior to posting and I am finding different people mentioning different gap sizes and some are using NGK, HK and OE NGK. So I just want to confirm which gap size should I go with. I am using the OE NGK 000-159-05-00. When I checked all the plugs, they're around 0.024" - 0.026". Some people say to leave it as it is factory gapped but from past experience, it is always good to check all the gaps. But I just don't know the definite answer as to what that size is.
Thanks!
