Airtec Motorsport Cast Alloy Inlet Manifold for GR Yaris
Airtec's cast aluminium intake manifold has been designed to be both strongand freer-flowing design measured an improvement in flow of 36% in comparison to the original.
More equal balance across the cylinders, which is crucial for safe and efficient fuelling as well as consistent power and torque.
A true direct replacement by utilising all the original fixtures and fittings, including the standard throttle body and therefore pipework.
Dyno Tested
The manifold was tested on our own demonstration Yaris GR fitted with a big turbo conversion, Syvecs ECU and all associated modifications. With no changes (no mapping or increased boost) a back-to-back test revealed the fitment of the manifold alone saw power increase from 405.2bhp to 415.0bhp – an increase of nearly 10bhp with no other modifications. Response also appeared to increase lower in the rev range and with mapping to suit, further increases would likely to be seen.
Note: the original engine cover will need trimming to fit or you can fit the AIRTEC Motorsport replacement engine cover.
Note: If you have an Airtec Motorsport catch can fitted, please tell us, as the breather fittings require different take off.
