Query: Better Starts, but first time I replaced the spark plug after two years.

Better Starts, but first time I replaced the spark plug after two years. So this isn't really a fair comparison unless I benchmark against a new usual spark plug.Bought two of these for my Poulan weed eater and Poulan Pro chainsaw. I needed to regap to .025". Starts are always on the sixth or seventh pull, compared to the usual 10-20 pulls. (Lowes has these for $8 instead of the listed $35 here, of which, I think is a pricing error here.)My thoughts are, these plugs are lacking a resistor making for hotter sparks, hence better burns and lower monoxide. Since we don't have AM/FM radios on our lawn equipment, we probably won't have any radio interference issues. I would also only install these plugs in lawn equipment or older engines, and exclude my newer 2005 Ford which is much more expensive to replace in case the plugs fail.
