Important Fitment Information

This bolt kit is intended for factory VGT-style exhaust manifolds only.

If you're installing an aftermarket T6 exhaust manifold, use Part Number: 101000S, which includes the correct hardware for T6 manifold applications.

Why Replace the Bolts?

Exhaust manifold bolts are exposed to constant heat cycles, vibration, and corrosion. Reusing old hardware can result in inaccurate torque, broken bolts, exhaust leaks, or the need to disassemble everything again. Replacing the bolts during a manifold installation is inexpensive insurance that helps ensure a reliable, leak-free repair.

Whether you're installing a stock replacement manifold or servicing your turbocharger, this hardware kit keeps the job moving without an unexpected trip to the parts store.
