    Anyone have any experience in changing and or experimenting with spark plugs for the tundras? Increased power or fuel economy?

    Unless your supercharge it not really. The old school days of playing with spark plugs is long gone. With the ECM controls the burn rate or the spark your limited.

    As long as the spark plugs have a nice color to them (even color) the spark plugs are at the proper heat range.

    I change mine every two years period. Regardless of miles on them. It gives me idea how the engine is running.

    Iridium (denso) you should be using if super charged.
