Mazdaspeed MS3 MS6 CX-7 Axela 2.3L BorgWarner EFR Turbo Oil Feed Line Kit｜4AN Braided

For Mazdaspeed 3 (MS3), Mazdaspeed 6 (MS6), CX-7, or Axela MPS 2.3L MZR DISI owners upgrading to a BorgWarner EFR turbocharger (such as 7064, 7163, 7670, 8374, 8474, 9174, 9180, 9280), a proper oil feed solution is essential. The factory K0422 hard line was never designed for advanced EFR turbos, and attempting to reuse OEM hardware risks fitment problems, oil pressure issues, or premature turbo wear.

This 4AN PTFE stainless braided turbo oil feed line kit is purpose-built for BorgWarner EFR conversions. Since EFR turbos are engineered with an internal oil restrictor, this kit is configured for a direct, unrestricted oil path, ensuring your turbo receives the precise lubrication it was designed for.
