Tom's Fuel Map Controller + TRD Racing Spark Plug

Why would you want colder plugs if you are not FI or advancing ignition timing?

You wouldn't.

Haha, not because it is TRD. I happaned to sit in one stock Yaris(regular Vitz, not RS) there with just Tom's controller and this plugs, I guess they were promoting this two product. The guy drove me around with +1 and 2 setting, no knock, power climb up very smoothly. Although I didn't see their dyno data, but just my butt dyno. That really convince me to buy and it wasn't super expensive like $600+ anyway.
