BorgWarner 11-13 BMW 135i/335i B03 Turbocharger w/Exhaust Manifold

What you get with this BorgWarner turbocharger kit is the turbocharger itself, pre-assembled with its exhaust manifold. This is a direct replacement unit designed for specific BMW models, aiming to restore or improve the performance of your original turbo system. It's built to handle the demands of turbocharged engines, helping to force more air into the combustion chambers for increased power and torque.

This particular turbocharger is BorgWarner's B03 model, a well-known unit in the performance aftermarket. It comes with the exhaust manifold already attached, which simplifies installation by reducing the number of separate components you need to handle. The manifold is designed to bolt up to the cylinder head, and the turbocharger is designed to connect to your existing intake and exhaust plumbing. BorgWarner is a reputable name in turbocharger technology, and this unit is built with their experience in forced induction systems. It's important to note that this part is not CARB approved and cannot be shipped to California due to emissions regulations.

When installing a turbocharger, it's crucial to ensure all oil and coolant lines are properly flushed and connected, and that the system is free of any air leaks. Using fresh, correct-spec oil is also vital for the longevity of the turbocharger. This unit is intended to be a direct replacement, meaning it should bolt into the factory location and connect to the factory exhaust and intake piping, though always refer to the manufacturer's installation guide for specific details and any required hardware not included.
