JDC Titanium Exhaust Manifold Stud Kit (Evo X)

Using the factory exhaust manifold bolts and studs with an aftermarket turbo can result in stripped or broken bolts and inadequate sealing force, which will result in an exhaust leak. This kit will allow you to properly seal the exhaust manifold to the cylinder head and will never rust or corrode! The JDC titanium stud kit is made from Ti6Al-4V (Grade 5) titanium and incorporates a hex key tip that allows them to be easily installed using an Allen wrench.

Torque Specs:

• Exhaust manifold to head: 37 ft-lbs + or - 3 ft-lbs.
• Turbo to manifold: 22ft-lbs + or - 1ft-lb.

Note:

• Please check the clearance on your manifold before ordering. Some manifolds will have less clearance than others. If you have a manifold with sharp angle bends straight out of the head flange, we recommend using six-point nuts, which will allow you to use an open-end wrench to tighten them. Twelve-point nuts would require a closed-end wrench to tighten and may not have enough room to get on the nut once the studs are in place. Check for clearance before ordering and you shouldn't have any issues.
