    +1, many options and depends on your mods. Most seem to stay with OEM or use Autolite, but you should search it for all the info to make your decision. Its almost as bad as what kind of oil should I use? Rockauto has good prices.

    About the only consensus on spark plugs is to avoid Bosch.

    If you haven't done any tuning I would only use OEM. Non OEM plugs can cause some odd seemingly unrelated things to start happening. It's just not worth the potential trouble.

    ^^There is no advantage with non oem or performance plugs if you have a stock tune, plus oem plugs are cheap!

    I disagree with the oem plug theory, ive used oems, and now iridium plugs which imo out perform oem plugs, i have yet to have a problem.

    Dennis Reinhart recomends the stock copper tip plug- The iridiums are a bit better ,but not a noticable diff. Autolite makes motor craft plugs [fyi]
