A simple way to replace the damaged or worn-out exhaust studs on the 3S engine. With the included anti-seize, these studs thread into the cylinder head and secure the manifolds with the stainless steel or copper locking nut. The studs provide a solid clamp force across the manifold and will work with any turbo or NA manifold application. These studs are high-quality, grade 8 Torx drive studs.
The upgraded copper washers provide a great locking nut on the studs to help prevent stud back-out. Additionally, copper washers help prevent seizing and stuck nuts when you go to remove the manifold, especially after many heat cycles.
This kit comes with 9 studs/nuts so this will work on all-year 3S engines. Earlier 3SGTE 7-bolt exhaust manifold customers will simply have two spare studs after installation.
