Factory exhaust manifolds on the 1994-1997 7.3L Powerstroke have seen decades of heat cycles. The castings crack and warp, studs break, gaskets blow out, and the resulting exhaust leak costs you boost and brings the familiar tick on a cold start. The KC Turbos 302873 kit replaces both manifolds on OBS 7.3L Powerstroke pickups with a stronger, better-flowing pair.

KC cast these manifolds from high-silicon molybdenum iron and made the casting and mounting flanges thicker than stock, so they resist warping and cracking and clamp evenly against the cylinder head. The runners are port matched to the head, and the kit bolts on in place of the factory manifolds with no modifications.

What you get:

• New driver side and passenger side upgraded exhaust manifolds
• Stainless steel manifold gaskets for both sides
• 16 OEM-style interference thread manifold bolts that resist backing out
• Built-in EGT probe port and the factory EBP tube port, each shipped with an NPT plug installed
• Thicker flanges and an enlarged sealing surface to cut down on hot spots and leaks
• Reworked up-pipe mounting face for better alignment and clamping
• Fits 1994-1997 Ford 7.3L Powerstroke OBS pickup trucks

Specs:

• Manufacturer part number: KC Turbos 302873 (OBS version)
• Material: high-silicon molybdenum (High-SiMo) cast iron
• Exhaust flow: over 20% more than stock manifolds, per KC Turbos
• Manifold bolt torque: 45 lb-ft (61 Nm)
• Up-pipe to manifold bolt torque: 18 lb-ft (24 Nm)
• Up-pipe to manifold bolts are not included; the factory hardware is reused

This kit suits 1994-1997 7.3L owners fixing a leaking or cracked manifold, and anyone adding power who wants a clean spot for a pre-turbo EGT probe. These manifolds are not designed for van applications. KC recommends replacing factory up-pipes that use donut-style gaskets and running a thread chaser through the head's bolt holes before installation. Buy with confidence. Verify fitment for your truck before ordering.
