The BD Diesel Exhaust Manifold Driver Side (1043006) is a high-quality upgrade designed specifically for the 2011-2019 Ford Powerstroke 6.7L engine. Engineered for improved durability and performance, this manifold is crafted from heavy-duty high-silicon ductile iron to withstand extreme temperatures and resist cracking, a common issue with stock manifolds. Its precision-cast design ensures optimal exhaust flow, reducing backpressure and promoting better turbo spool-up, which can contribute to increased horsepower and efficiency. Ideal for both stock and modified applications, the BD Diesel manifold is a direct bolt-on replacement for the factory unit, making it a reliable choice for Powerstroke owners seeking enhanced reliability and performance.
