KC Turbo - Upgraded Exhaust Manifolds - 1994-1998 (OBS) Ford 7.3L Power Stroke
Part # 302873
Increase your truck's reliability and performance with the all-new KC Upgraded Exhaust Manifolds for your Ford 7.3L Powerstroke. These Upgraded Manifolds are designed for the 1994.5-1998 model years and include the factory EBP Tube provision alongside included EGT Probe provision. These two ports comes with bungs pre-installed if your truck does not have an EBP tube or EGT probe.
The factory exhaust manifolds have a tendency to wear out, deteriorate, and crack over time. This deterioration creates uneven clamping pressure, often leading to warped manifolds, broken studs, blown gaskets, and eventually, performance loss due to exhaust leaks.
The all-new KC Turbos Upgraded Exhaust Manifolds for your 7.3L Powerstroke addresses these issues with a completely redesigned manifold that utilizes increased mounting flange thickness for an even seal against the cylinder head. Made from high-silicon molybdenum cast iron, our upgraded manifolds are significantly more resistant to thermal warping and cracking under extreme conditions.
Internally, the exhaust runners have been port-matched and redesigned to increase flow by over 20% compared to stock manifolds. This not only improves overall performance but also reduces back pressure and enhances turbo efficiency. The bolt mounting flange thickness has been increased significantly to eliminate common stress points and ensure reliable sealing, while the up-pipe mounting face has been re-engineered for better alignment and clamping under load. The larger, fully machined sealing surface minimizes hot spots and helps prevent cracking due to uneven heat distribution.
Each kit includes 16 Updated OEM-Style Interference Thread Exhaust flange bolts to ensure proper thermal expansion and even torque retention. This long term performance solution improves upon the OEM castings and hardware to keep your 7.3 Powerstroke on the road for longer.
Whether you're addressing the common failure points on your factory exhaust manifolds or pushing your 7.3 Powerstroke for more power, the KC Turbos Upgraded Exhaust Manifold kit for the 7.3 Powerstroke is built to last and perform.
These manifolds are designed to fit directly in 7.3 Powerstroke equipped OBS, E99, and L99 pick-up trucks. These manifolds are NOT designed to fit van applications.
Benefits Explained:
-
Reinforced High-Stress Casting: Increased wall thickness in critical heat and stress-prone areas helps resist cracking, warping, and thermal fatigue.
-
High-Silicon Molybdenum Construction: Upgraded High-SiMo material provides superior high-temp strength, thermal stability, and durability compared to conventional cast iron replacements.
-
Optimized Exhaust Flow Path: Smoother internal transitions reduce turbulence and restriction, improving exhaust-gas velocity and flow into the turbocharger.
-
High-Flow Port Geometry: Redesigned, port matched, and enlarged exhaust ports improve flow capacity & minimize restrictive transitions from the cylinder head into the manifold.
-
Integrated EGT Probe Port: Built-in provision for an exhaust gas temperature probe sensor provides a clean location for accurate pre-turbo EGT monitoring.
- Interference Thread Mounting Hardware: Ensures that the exhaust manifold mounting bolts will not back out after installation.
