Rotomaster A1383802N Turbocharger Exhaust Adapter

Rotomaster Turbocharger Exhaust Adapter

Rotomaster A1383802N is a new turbocharger exhaust adapter built as a direct O.E. replacement for select Ford diesel applications. It replaces the factory adapter with exhaust back pressure valve (EBPV) function to help restore smoother exhaust flow through the turbine housing.

Compatible with 1999-2003 Ford F-250 Super Duty, 1999-2003 Ford F-350 Super Duty, and 2000-2003 Ford Excursion applications, this cast iron adapter is made to OE-grade material standards for durability and consistent fitment.

Key Features

• Direct O.E. replacement for the factory turbocharger exhaust adapter
• Eliminates the factory exhaust back pressure valve assembly
• Improves exhaust flow by reducing restriction at the turbine inlet
• Cast iron construction for durability in high-heat exhaust service
• OE-grade material selection for long-term service life
• Fits applications with wastegate and without mounting pedestal, where noted
• Part number: A1383802N

Product Details

Rotomaster’s New Turbocharger Exhaust Adapter line focuses on replacing restrictive factory components that can contribute to soot-related sticking or electrical faults in the EBPV system. By removing that restriction, A1383802N provides a smoother path for exhaust gases entering the turbine wheel, which helps maintain turbo response and reduce exhaust backpressure. This part number, A1383802N, is a practical OE-style solution for Ford F-250 Super Duty, Ford F-350 Super Duty, and Ford Excursion diesel trucks that need a replacement exhaust adapter with the correct factory-style fit.

This part cross-references Monroe Shocks & Struts (e.g., N138802A) for the same application.

What It Helps Address

• Sticking or restricted exhaust back pressure valve operation
• Exhaust obstruction caused by soot buildup
• Higher exhaust gas temperatures from excessive restriction
• Reduced turbocharger response
• Premature wear from prolonged exhaust backpressure

Installation Notes

Compatible With 1999 Ford F-250 Super Duty and 1999 Ford F-350 Super Duty from engine #896,813 with wastegate and without mounting pedestal. Compatible With 2000-2003 Ford Excursion, 2000-2003 Ford F-250 Super Duty, and 2000-2003 Ford F-350 Super Duty with wastegate included and without mounting pedestal. Verify engine configuration and mounting style before installation to confirm the correct application for A1383802N.
