So, putting all new plugs and wires on my '04 GTP. Also, doing headers in the very near future with a full 3" exhaust. Future mods this summer are rockers, e85, a slight pulley drop, and of course a tune.

Can I plan for these mods and run a certain type of sparkplug suited for those mods, now, or will I just have to change it in the future to accommodate those mods? Whichever one, looking for recommendations for the better sparkplug/wires combo.

Thanks
