yup.
By having only a sharp tip it forces the spark energy forward to the tip. instead of directly inbetween the electrode tip and the inside of the ground strap, directly across from the electrode.
its a simple way (manufacturing standpoint) to make the standard plug alil better.
This puts the spark out further into the air fuel mix, igniting the incoming charge more efficiently.
I like to sharpen the entire strap directly above the electrode. this causes the spark to "dance" around the entire end of the ground strap, increasing the spark size and intensity dramaticly.
you can view this your self very easily. take 2 new plugs, sharpen one up.
Do this at night for best visibility with all lights turned off.
pull wire #1 or #2 which ever is easyer for you to get to.
Slip in the non sharpend plug into the wire. Hold it against the block with insulated pliers.
Hold the boot not plug for more insurance from being shocked IT EFFIN HURTS!
Have someone fire up the engine. watch the psark intensity. kill engine, swap to sharpened plug. fire engine.
You will see a dramatic difference.
This plug is as close as it gets to what I do to mine with a file. but cost ALOT more.
Im cheap and like to do my own *******. click to enlarge it then zoon in more. IF you use inet explorer click the zoom on bottom right corner of window.
You will see they added to 45* cuts instead of 90* corners and that they are very sharp on the inside and outside.
The more sharp surfaces for spark to jump, the more it will jump. thus as by produict increasing the size and power of that spark. Especially with a high output coil.
heavy oil is just something I personaly do. I feel since its thicker it "holds" onto any debris longer than thin oil. thus helping get rid of it during oil changes. That and seafoam is a solvent it dillutes the oil, I figure alil thicker oil while running seafoam is never a bad thing.
That and castrol 20/50 is on every shelf in america and generally cheaper.
