7.3 Powerstroke Early 99 Up-Pipe Collector Manifold – Ford F81Z-6K854-DA

Genuine Ford OEM Up-Pipe Collector Manifold (Y-pipe) for Early 1999 7.3L Powerstroke engines.

This is the factory collector that joins the left and right up-pipes and feeds exhaust into the turbocharger. It is a direct-fit replacement for the original part and is required when the stock collector is cracked, warped, seized, or damaged during up-pipe service.

Key Details

• OEM Part Number: F81Z-6K854-DA
• Application: Early 1999 7.3L Powerstroke only
• Build Date Cutoff: Fits engines built on or before 12/7/1998
• Function: Connects both up-pipes to the turbo inlet
• Construction: Genuine Ford OEM casting for correct fit and durability

Why This Part Matters

Early 99 trucks use a unique collector design that is not interchangeable with 1994–1997 or late-1999–2003 versions. Using the wrong collector will cause fitment and sealing problems. This OEM piece restores the correct geometry and sealing surfaces so your up-pipes (stock or aftermarket bellowed) bolt up properly and seal reliably.

Ideal when:

• Replacing leaking or damaged factory up-pipes
• Installing aftermarket bellowed up-pipe kits that reuse the OEM collector
• The original collector is seized or broken during removal
• Performing a complete turbo or exhaust system service

Fitment Note

Confirm your engine build date. This manifold is only for Early 1999 (build date 12/7/1998 and earlier). Late 1999 and newer 7.3L engines use a different collector.
