indexing plugs

[sheerider11]

anyone do this on there banshee?? I know that its big in high horsepower cars. basically its getting the plug to face the way you want so when it ignites it can burn a certain pattern. I heard you can squeak a little power out of this.or is this one of those things that people say it helps and they just have a prefrence?

Take plugs out of box, install, ride...... Nothing more needed

I know that. I do check the gap tho. I've had a batch that got smashed, but has anyone done this? or heard of people doing it?

Sounds like a waste of time. Dont think it much matters which way your plugs face.

it is a hemispherical shaped dome. the reason you index a car plug is because the combustion chamber is no where near perfectly round. by indexing they are attempting to create a better burn pattern (truer burn) there is 0 to gain by indexing a hemispherical dome. same reason "hemi" engines were so popular. they get their name from having the plug in the center of the hemi-spherical dome.

That's the answer I was looking for. Thanks.
