Toyota 1JZ-GTE / 2JZ-GTE Exhaust Manifold Stud Nut Kit

This exhaust manifold stud nut kit is made for Toyota 1JZ-GTE and 2JZ-GTE turbo engines using factory twin turbo manifolds, single turbo manifolds, or aftermarket exhaust manifolds.

JZ engines generate high exhaust heat and vibration, especially in high-boost street, drift, and drag setups. Worn studs, reused nuts, or weak hardware can lead to manifold leaks, loose fasteners, and sealing issues around the exhaust manifold or turbo manifold flange.

Each stud features a 5mm inner hex design for cleaner installation without damaging the external threads. The copper-coated top-lock nuts help resist loosening under heat cycles and vibration, making this kit suitable for rebuilds, turbo upgrades, and single turbo conversions.
