DESCRIPTION
The "Rally 2" style Hood Vents enable to obtain two major benefits from your GR Yaris:
-
Reduce Engine Temperatures:
Oil Temperatures cooler by >-10°C (especially noticeable on track!!)
Air Intake Temperatures drop by various degrees, thanks to better air exchange. -
Increase Front End Grip:
reduces the GRY's massive Aero Lift by extracting aerodynamic pressure from under the hood and transmission tunnel, to over the top of the car.
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, extending both the engine and ancillary component's life.
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 water-proof from factory.
INSTALLATION NOTES: the installation of this kit requires cutting both outer and inner front hood skins (Alu sheets), then bonding to the hood with car body shop structural bonding adhesive. The mesh grille is bonded to the outer hood skin, from inside the hood.
No drilling or screws are necessary!
For cosmetic-only fitment, the vents may be bonded to an uncut bonnet. Functional cooling and air extraction require cutting both bonnet skins.
Installation instructions and blueprints are provided in our download page.
PAINTING: while painting is possible, the vents are delivered in Satin Black, UV resistant coating.
INSTALLATION DIFFICULTY: difficult, requires a professional body shop.

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.
Do I need to cut the bonnet for functional cooling?
Yes. Functional installation requires cutting both bonnet skins and structurally bonding the vents and mesh. Use a professional body shop. No drilling or screws are required. 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.
