P/// Piras Motorsport attack hood vents Toyota GR Corolla

Product detailed description

Based upon our first-hand “GR” experience gained thru the development of the GR Yaris hood vents kits, we set out to engineer a unique hood vent kit that could complement the GR Corolla “Core” version with better front-end aerodynamics and cooling, while being compatibe with the GR Corolla vented hood.

This kit consists of three (3) separate parts: Left vent, Right vent & Center vent: while the principle of function of the lateral vents concurs greatly to reduce front end lift, the center vent is strategically positioned to provide the best possible heat extraction from the radiator package. The results translate in: 

• 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 Corolla 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, tested on various GR Corolla’s, 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.

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!
Cutting the hood is optional, the parts may be glued/bonded to the hood.

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.
