Professional body-shop installation is required. Proper installation involves cutting the outer and inner bonnet skins, then structurally bonding the vents and aluminium mesh grilles.
The "Rally 1 - WRC" style Hood Vents represent the pinnacle of aerodynamics and cooling for your GR Yaris, obtaining the following benefits:
-
Reduce Engine Temperatures:
Oil temperatures reduced by more than 10°C, especially during track use.
Air-intake temperatures are reduced through improved airflow and heat evacuation. -
Increase Front End Grip:
Helps reduce front-end lift by evacuating under-bonnet and transmission-tunnel pressure over the top of the car.
-
Reduce Engine Temperatures:
Hood vents are essential for anyone that lives in hot climates or is driving a GR Yaris to its full potential. This kit reduces the under-hood temperatures, helping extend the service life of the engine and ancillary components.
Chances of experiencing the dreaded LSPI engine failures, that are spiked by very hot oil temperatures, are also reduced.
COLD WEATHER & RAIN: this kit has been extensively tested on over 100 GR Yaris over hundreds of thousands of kilometres, and we confirm that no issues from rain or water have been encountered. For this reason, we decided not to provide rain covers, as the impact on the kit’s function would be too great. Lesser kits, that position vents on top of the engine, have issues with flooding the coil packs, but we have engineered the product to OEM levels. Fuse box and all other electrical connectors are waterproof from factory.
Professional body-shop installation is required. Proper installation involves cutting the outer and inner bonnet skins, then bonding the vents and aluminium mesh grilles with structural body-shop adhesive. No drilling or screws are required. Installation instructions and cutting templates are available on the Downloads page. The vents are supplied in a UV-resistant satin-black finish and may be painted.

Frequently asked questions
Which cars does it fit, and what is included?
GR Yaris Gen 1 and Gen 2. The kit includes left and right vents, black aluminium mesh, an ECU-harness protection liner and a downloadable fitting template.
Does installation require cutting the bonnet?
Yes. A professional body shop must cut the outer and inner bonnet skins and structurally bond the vents and mesh. No drilling or screws are required. Structural adhesive is not supplied.
Are rain covers or painting required?
Our testing has shown no rain-related issues, so we do not supply rain covers, which restrict airflow. The vents arrive in UV-resistant satin black and can be painted.
