Mazdaspeed MS3 MS6 CX-7 Axela 2.3L K0422 Turbo Oil Feed Line Kit｜4AN Braided

The Mazdaspeed 3 (MS3), Mazdaspeed 6 (MS6), CX-7, and Axela MPS equipped with the 2.3L MZR DISI turbo engine rely on a steady and clean oil supply for their factory K0422 turbochargers. Over time, the OEM rigid feed line is prone to heat-soak fatigue, corrosion, or hairline cracks, which can lead to oil leaks, pressure loss, or even catastrophic turbo damage. This 4AN PTFE stainless braided turbo oil feed line kit is engineered as a direct replacement and upgrade for the factory line. Designed to maintain consistent oil pressure and optimized flow to your K0422 turbo, it provides long-term durability and reliability—making it ideal for preventative maintenance or when replacing a failing OEM hard line. ‣ Application: Fits Mazdaspeed 3 / Mazdaspeed 6 / CX-7 / Axela MPS 2.3L engine with K0422 turbo‣ Replaces OEM feed line – eliminates leaks, brittle tubing, and oil starvation issues‣ Optimized 1.8mm restrictor fitting – ensures correct oil pressure for K0422 journal-bearing turbos‣ 4AN P
