Personally I wouldn't use a gap as big as .035. The HT side of the ignition can be a weak point and the spark will try and go anywhere except across that plug gap. It takes a lot more energy to jump a 35 thou gap than a 25 thou gap.

I have always used the autolite 216s. They work ok for me. I will probably try some NGKs next time, but I can't see how they will be better. As long as they work ok they will be as good as the 216s.

You need to have a plug type that is giving problems to then state that the replacements are an improvement.

NGK are a quality brand though and are an OEM supplier to the automotive industry.
