Anyone ever change to different spark plugs??
The C32/55 guys are talking about how big a difference changing to different plugs made.
Anyone have any experience?? If they are claiming that big a difference with their motors....we should see??

Big difference? Doubt it.
I'm gonna change them this summer and swap in Denso Iridium IK16s. Bit pricey, but I've heard nothing but good things from them.
You shouldn't feel too much of a difference. To maximize its potential, you might want to try Evosport plug wires. Still I doubt a BIG difference, but you'll probably feel something.

The stock sparkplug crosses over to an NGK Iridium BKR5EIX-11 (Stock #5464) which is the same style and heat range plug as the Denso IK16. One step colder sparkplug for an NGK Iridium would be a BKR6EIX-11 (Stock # 3764).
I have ran both the Denso's and NGK Iridiums in my Supra and have not measured any performance difference on the dyno nor any difference in general street driving. The only difference I have found is the price. The Denso's are ~$12 each and the NGK Iridiums are ~$7 each.
The NGK Iridium plugs are available for ordering through any Advance Auto Parts at $6.9x per plug.
