Technical Description

This turbo oil feed line kit is designed for Mazdaspeed 3, Mazdaspeed 6 and Mazda CX-7 models equipped with the 2.3L MZR DISI Turbo engine and converted to a compatible BorgWarner EFR 6258, 6758 or 7163 turbocharger. It provides the external pressurized oil-supply connection between the engine block and upgraded turbocharger.

Converting from the factory K0422 turbocharger to a BorgWarner EFR unit changes the turbo oil-inlet connection. The original K0422 oil feed pipe is not designed to connect directly to the EFR center housing, requiring compatible fittings and a flexible oil-feed route for the conversion.

This GryphonTek kit uses a flexible -4AN PTFE hose with a 304 stainless steel outer braid. The supplied EFR-specific turbo-side fitting provides a non-restricted oil-feed connection for the listed applications, while the matching engine block adapter connects the braided line to the factory engine oil source.

Key Features

  • Application-specific turbo oil feed conversion for listed BorgWarner EFR turbochargers
  • EFR-specific turbo-side oil fitting without an additional external restrictor
  • Flexible -4AN PTFE hose with a 304 stainless steel outer braid
  • Includes the engine block adapter and sealing washers required for the external oil-feed connection
