Why Replace the Hardware?

Exhaust manifold hardware lives in one of the hottest areas of the engine. Years of extreme heat, vibration, and corrosion can reduce clamping force and make old hardware difficult to remove without damage. Installing new studs, nuts, spacers, and washers when replacing your manifold helps ensure a proper seal, minimizes the chance of future exhaust leaks, and makes the repair more reliable.

If you're installing an aftermarket manifold or turbocharger, replacing the hardware is inexpensive insurance against future downtime.
