    Side gapping and Indexing

    Old timers that know what I'm talking about, discuss. Does it help any little bit to do this to the plugs?

    they are the biggest Men I have ever seen. I
    wouldn't want to fight them!

    Me: That is why no one will remember your name!

    All my research points to this combination helping but not being worth a hassle. One of those "ever bit counts" thing

    yeah, indexing allows for a consistent flame front each time it fires

    I read that aiming the plug gap towards the intake valve doesn't really do the trick. The key is finding the sweet spot which is impossible to the average joe blow. You can get lucky I guess

    This what I've gathered as well. Varies from motor to motor. The jeep guys are all into it, making a bigger difference at higher rpms. All in all, not worth the hassle.

    Suggestion: If you are particularly irritated by another member's posting habits and are constantly fighting the urge to flame them, you can click on that person's profile, and select "Add to ignore list." This will make that person's posts invisible to you.

    I'm doing it on a scooter and a snowmobile

    SR20 guys are swearing by this (MPG) One guy actually dyno'ed before and after 3 times average and he said he picked up 7rwhp

    That is within the error of the dyno but at leasts he tried.

    If it helps with 1 mpg on my toys its worth it since changing plugs on my toys are too easy.
