Getting time to freshen up these, which is the best for my setup? Bolt-ons, macs/ORY/slp dd/cutout, vig3600, f1 cam. Don't plan on spraying at all so NA combos are what I'm looking for. Currently have NGK TR55/stock wires, plugs have been in a little over 50k miles...... I know

most will tell you to keep running the ngk tr55s. i read on ngks website to go colder for every 100 extra hp, so im going to try some ngk tr6.
