A Free Mod Worth A Few H.P.
In my quest to squeeze a few more horsepower out of my car I came across this good article.
Rounding off the end of the side electrode as shown here reduces the peak temperature seen by the electrode so moving away from the possibility of detonation from this source. Also, in the relatively swirl-free conditions that exist at low rpm, this form gets the charge burning more effectively. Be sure to cut the electrode so the end of the tip is no further than half way over the center electrode. If plug life is not an issue cut it so it is between a 1/5 and 1/3 of the way over the center electrode.

i've seen that in some books before, i have also seen where you cut it so it is straight, but that seemed weird to me.....
supposedly in the book i read you can pick up like 5 hp from it... but whos knows.....
it was one of those mustang POWER mauals you'll see at barnes and noble and other fine retailers.....

Snake oil. How the hec is that gonna give any noticable gains by shaving an ass hair off the electrode? The goes along the lines of the Tornado and Split fire plugs.

Its legit.
Sharp edges in the combustion chamber are a no-no since they can create hot spots that can cause pre-ignition.
One of the things they used to have me do at the speed shop when I was a kid was file, sandpaper and beadblast the plugs that went in the higher compression race motors.
The other hot tip is to slightly bevel the edge of the electrode and plug body too.
The rule is no sharp edges since they will become the hottest spot in the cylinder.
If you really want to be anal about your plugs, you should also index them so they do not impede the path of the flame front.
