The Mazda RX-7 FC equipped with the 13B rotary engine and stock HT18S-2S turbo relies heavily on a stable and unrestricted oil supply. Over time, the OEM hard line can corrode, crack, or leak due to heat cycles and vibration—leading to inconsistent lubrication or even turbo failure.

This 4AN PTFE stainless braided turbo oil feed line kit is designed as a direct replacement upgrade for your FC3S. It delivers consistent oil pressure, improved flow, and added durability compared to the factory line, making it an excellent preventative maintenance choice.

⚠️ Note: Not for FD RX-7 applications.
