1JZ GTE VVTI Billet Valve Covers
 
Introducing our latest evolution of billet valve covers for the legendary Toyota 1JZ GTE VVTI engine — engineered for precision, durability, and a flawless OEM-plus appearance.
 
Developed using advanced 3D scanning technology, each set begins with a high-resolution scan of genuine OEM 1JZ-GTE VVT-i covers. This ensures an exact external profile while allowing us to integrate modern improvements such as AN-10 ports for external catch-can setups and internal baffle plates for optimized crankcase ventilation.
 
These billet covers retain compatibility with the factory plastic engine cover (minor trimming required at the rear to clear the AN fittings), preserving the clean factory look enthusiasts love.
