Upgrade your Mazda MX-5 Miata MK1, MK2, or MK2.5 to the next level of performance with a BorgWarner EFR 6258 or 6758 turbocharger.

These advanced EFR turbos are designed for high response and durability—but to perform at their best, they require a stable, unrestricted oil supply configured for EFR’s internal restrictor system.

This 4AN PTFE Teflon stainless-braided turbo oil feed line kit delivers the correct flow characteristics specifically for EFR turbos. Unlike conventional setups that rely on external restrictors, this line provides a direct feed path, ensuring proper oil pressure balance and long-term turbo health during high-boost operation.

Perfect for N/A-to-turbo Miata builds, this kit includes all fittings and adapters needed for a clean, professional-grade installation.

‣ Application: Mazda MX-5 Miata MK1, MK2, MK2.5 with BorgWarner EFR 6258 / 6758 turbo conversion
‣ EFR-compatible configuration – supports turbos with built-in oil restrictor (no external restrictor required)

‣ Complete bolt-on kit – all fittings included, no custom fabrication required

The BorgWarner EFR 6258 / 6758 turbos are precision-engineered for rapid spool and high efficiency—don’t risk that performance with the wrong oil feed.
This Gryphontek oil feed line kit ensures accurate, stable lubrication that keeps your turbo performing at peak response and reliability.

📦 Order today and complete your Miata’s EFR turbo upgrade with the correct oil feed solution designed for long-term performance.
