Autolite vs NGK Anyone running NGK R5671A-9? I have been running autolite 3933's and have been thinking about trying NGK's. I have never hurt anything with the autolites but have heard the ngk's were a little easier to read. Opinions?

The NGK's are easier to read. From what I understand the NGK's are made out of "softer" material and they are a little more forgiving than an Autolite if you do have an issue.
I have not had any issues with the Autolites but the NGK's are definitely easier to read.
