90-Degree Turbo Elbow Installation Kit

When upgrading your CAT 3406E, C15, or C16 with a performance turbo and manifold, the PDI 90° Turbo Elbow Kit is a required component to ensure proper fitment and optimal airflow.

This 90-degree elbow is engineered to provide balanced exhaust airflow, helping maintain efficient turbo performance while keeping exhaust temperatures within the elbow under control. By improving the way exhaust gases move through the system, this elbow helps support better turbo efficiency and overall engine performance.

Unlike fabricated elbows that rely on welds, this component is fully cast, eliminating the risk of weld failures and improving long-term durability under extreme heat cycles.

When paired with a PDI turbo and exhaust manifold, this elbow helps maximize the performance benefits of the upgrade — including increased horsepower, improved torque, better fuel efficiency, and smoother drivability.

If you’re installing a PDI turbo and manifold on a CAT 3406E, C15, or C16, this 90° Turbo Elbow Kit is required for proper installation.

Required For:

• CAT 3406E

• CAT C15
