I think you have a wrong idea how air - fuel - spark mixture works in regards to power.

More fuel is not equal to more power unless you have more air coming. That's why on forced induction you need more fuel since the turbo is pushing more air into the engine. The same theory applies to more fuel needs less spark to detonate that's why cold plugs are used.

In my opinion these parts are not for stock yaris engines. These are parts designed to match other parts like a turbo setup.

If you are running stock or few mods like an upgraded intake and exhaust this is just waste of money for less power.

I know I'm bringing this thread back from the dead. But, I was wondering if there has been anyone to test it out on the dyno? I'm kinda guessing that this product never caught on it's not worth anything. Either way just wanna know what the outcome of this was.
