1JZ GTE Non VVTi Slim Billet Valve Covers

Introducing the ultimate upgrade for your 1JZ GTE Non VVTi engine — the Ichiban Engineering Slim Billet Valve Covers. Designed to eliminate the weaknesses of OEM cast covers, these precision-machined billet covers deliver unmatched strength, fitment, and style.

Using advanced 3D scanning technology, we recreated the original 1JZ-GTE Non-VVT-i geometry to ensure a perfect fit while integrating key performance improvements. Each set is CNC-machined from aerospace-grade 6061-T6 billet aluminum, making them virtually unbreakable — even under over-torque or extreme heat.

These are the slim version covers, offering a sleek, compact profile. They are not compatible with OEM plastic covers. If you prefer to retain the factory top cover, please see our OEM-style billet version.
