Weldspeed - GR Yaris Intake Manifold

Weldspeed have been working away in secret over the past 18 months developing, testing and trialing our brand new Intake Manifold to suit the Toyota G16E-GTS engine from the GR Yaris (and the anticipated GR Corolla).

This product represents our attempt at a clean-slate design with the sole aim of improving upon the OEM Intake Manifold in as many ways as possible. We are able to achieve this with increased plenum volume & optimised runner geometry for midrange torque output and improved Volumetric Efficiency at higher engine speeds.

Back-to-back dyno testing has shown an 11% increase in torque and a 7% increase in horsepower with NO OTHER CHANGES. Peak torque was also achieved much earlier than with the OEM Intake.
*Test vehicle fitted with Motec ECU running closed-loop AFR.
*NOTE: As always, any changes to your intake tract should be monitored by a tuner for safe operation and maximum performance gains.

This Intake Manifold is a no-compromise performance part that in specifically designed to increase horsepower and torque in your G16E-GTS powered GR Yaris.

Standard finish offered will be raw cast aluminium, with options for powdercoating.
