Wow
Seriously the Denso Iridiums are the best for the TC. Theres this place Bumper 2 Bumper where I live and they sell these new Autolite XP plugs and the guy there told me that those will outperform any plug. If you say the Denso's are fine I wont waste my money then. Thanks

trust me, alot of people usually upgrade to denso iridium spark plugs. toyota gave them to us stock. ngk and borsch are good brands too. but nobody wants to change the spark plugs on their tc unless they are going turbo and want a colder heat range.

Unless you go heavy PSI from F/I application the stock Denso iridium plugs work just fine. In fact I've tried the Bosch Platinum +4 plugs and they actually started messing with my MPG and engine startup.

Case in point:
The Camry engine, same configuration as the TC, 2.4 ltr is about 50% Denso.
Either way, Denso or NGK you have an excellent oe plug. I wouldn't change a thing unless you have higher end engine mods.

you can get them at other auto parts stores.. but from what I've seen, the toyota part is in better shape (side electrode bent more precisely) than the auto part stores part.
stay with the toyota part, unless you want to buy one of each and see the differences. I know i have personally observed the differences.
EDIT UPDATE: Just took a look at a friend's tC, NGK Laser Iridium were in there from the factory! So the part the toyota dealer is selling is Denso. If you want the NGK then most auto parts store can get these or have them in stock.
