hey guys! i just have a couple question! . i finally took care of my car! ,yesterday i replaced my sparkplugs and i could not buy the NGK but i got autolite ,they were $2.39 each! and when i look in the computer that same plug was good for trailing and leading! ?is this possible?. the car is runing fine! what do you guys think!

 

I think you should have used the correct NGK plugs.

Are the autolight multi-electrode or just a electrode ring??

Single electrode plugs tend to not burn very well in a rotary motor (spark tends to not last long enough and gets blown out).

 

I wouldn't use autolite's. They are cheap, and don't last long.
