Spark plugs

[PLP]

Based on the spark plugs selection, is there any difference in terms of performance (I mean actually something felt, like low end torque, not necessarily high end power), or smoothness of the engine.

I started a thread in the Technical subforum, so maybe these two should be merged...

With proper plugs for the application.
Of the proper heat range
Gaped properly.
You will not feel any difference from one make or type of plug to another.
