Yaris Intake Manifold

[PHXDEMON]

I would be interested in an intake that had a flange for a larger throttle body. Anyone who has installed an intake on our cars sees how tiny the throttle body is on our motors. I think If we were to swap to a larger throttle body off like a TC or a corolla then there would be a much more noticible difference in HP

The prototype intake was made with a flange to accept the larger Xd throttle body. The throttle body upgrade was only worth 1-2 hp-not enough to justify the expense of purchasing the new or used throttle body. Since I know whatthe next question will be (we've already covered this), the larger Xd throttle body will bolt onto the stock intake but sealing will be an isue since the hole in th eintake is much smaller than the hole in the throtle body. Ditton fo rthe rubber o-ring throttle body gasket. Besides, you will need to enlarge hole in th eintake which will be difficult since there is little wall thickness. An adapter plate can be made to facilitate the swap, but again cost versus power gain is not very favorable.
