Spark plug question
I was looking at acdelco.com and noticed that stock plugs, R45TS, have an extended tip. (same plugs from the factory)
The ones I bought today ,R44T, are one level colder and are shorter, WITHOUT an extended tip.
Will this hurt performance?

)

Just my personal experience. The further in the plug can reach, the better the combustion from the spark. Unfortunately, long-tip plugs tend to be hotter. Plugs that are too hot create detonation problems or make them worse.
Engines that REALLY respond to a long-tip plugs are...LAWNMOWERS! It's amazing how much better any Briggs & Stratton engine will run if you chuck the J-8 plug and put in a really long-tip plug. My chainsaw runs and idles much better with a longer-tip plug.
