I have used NGK and Autolites and both have never failed for me, but I prefer the Autolites.

thanks for the replies i went ahead and got some autolites

I like NGK plugs.

Autolites here 2

I used NGK & converted to same heat range to Bosch Platnum. Works great!!

NGK's are easier to read.

Autolite made in the USA
