Seems like a lot of work to achieve little to no gain (on a ranger).

It could mean a smoother idle. I think its worth the extra work to smooth out the idle in my truck. I'm in it so much and anything to make the experience a little better is worth it in my book.

Christian, I'd say go for it. It can't hurt to try, and I'm sure those washers aren't too expensive.

We do this on the Dragster, but it won't make much difference on a OHC motor, or a hemi, where the plug is pointed straight down at the top of the piston. On a old school OHV motor, where the plug comes in at and angle, you want to point the opening down towards the top of the piston for the best swirl action in the flame. But with high swirl heads, more than 2 valves, and the plug aimed straight down, indexing them won't make enough of a difference to be worth the time. You'll get more gain from taking a **** before driving.

It would prolly make a difference on the 3.0 and the 4.0 OHV motors though, so I'm not saying it won't work, cause it will, I'm just saying it won't do anything for certain motors.

I'm not really looking for a gain. I know something as simple as this won't give me much of a gain if any. I may do this to see if it will help improve my idle. If nothing happens then all well. Its $20 and a few hours of my time if I even decide to do it.

related or unrelated? You have to make the call.

Heres a piston for a Direct Injection gas engine. Its very wierd looking. It has to take the gas (sprayed at 2200psi?) and distribute it thoughout the chamber for an efficient burn.
