AFE BladeRunner Exhaust Manifold Ductile Iron 15-19 Ford 6.7L Powerstroke

Are you looking to upgrade exhaust flow, durability, and long-term reliability? The aFe Power BladeRunner Exhaust Manifold is constructed from heavy-duty ductile iron. Designed to replace the restrictive factory manifold, this upgraded casting helps reduce common failure points such as cracking and warping under high heat and sustained load. The internal runner design is engineered to improve exhaust gas velocity and balance flow to the turbocharger, supporting faster spool-up and more consistent boost response in both stock and modified applications.

Built for demanding work environments and performance-driven setups, the BladeRunner manifold focuses on strength where factory units typically fail. Thick-wall ductile iron construction improves resistance to extreme thermal cycling, while precision-machined flanges ensure a secure, leak-resistant seal at the cylinder head. The result is a direct-fit upgrade designed to improve exhaust efficiency, increase reliability, and extend service life in your SuperDuty.
