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.
