Rotomaster A1383801N Turbocharger Exhaust Adapter

Rotomaster New Turbocharger Exhaust Adapter

Rotomaster A1383801N is a new turbocharger exhaust adapter built as a direct O.E. replacement for applications that use an exhaust back pressure valve (EBPV). It replaces the factory adapter with a smoother exhaust path to help reduce restriction, support lower exhaust gas temperatures, and maintain turbocharger response.

Key Features

• Direct O.E. replacement for the factory turbocharger exhaust adapter
• Eliminates the exhaust back pressure valve from the exhaust path
• Improves exhaust flow by reducing restriction
• Cast iron construction for durability
• O.E.-grade material selection for long service life
• Designed to help prolong turbocharger service life
• Inside diameter: 2.83 in; outside diameter: 4.25 in
• Seven-bolt mounting pattern

Product Details

This Rotomaster New Turbocharger Exhaust Adapter is engineered for 1999-2003 Ford F-250 Super Duty, 1999-2003 Ford F-350 Super Duty, and 2000-2003 Ford Excursion applications listed without a wastegate or mounting pedestal. Part number A1383801N replaces the factory adapter that uses an EBPV, helping restore a cleaner exhaust exit through the turbine wheel. This part cross-references N138801A for the same application.

Common Issues It Can Address

• Sticking exhaust back pressure valve caused by soot buildup
• Faults related to the EBPV electrical signal
• Exhaust restriction at the turbocharger outlet
• Higher exhaust gas temperatures from restricted flow
• Reduced turbocharger response caused by exhaust obstruction
