Weldspeed GR Corolla Intake Manifold

Our G16E-GTS Intake Manifold 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 increase in torque and 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.
*Secondary testing has confirmed similar results with OEM ECU.
*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 bolt-in performance part that in specifically designed to increase horsepower and torque in your G16E-GTS powered GR Yaris or GR Corolla. Standard finish offered is raw cast aluminium, with options for powdercoating. SHIPPING:We recommendthe International Courier service and is calculated at check out.
