Technical Description

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.

‣ Application: Mazda RX-7 FC3S 13B engine with stock HT18S-2S turbo
‣ Replaces aging OEM feed line – eliminates leaks and brittle factory tubing
‣ Optimized restrictor fitting – ensures proper oil flow for HT18S-2S turbo
‣ 4AN PTFE Teflon stainless braided hose – heat, oil & pressure resistant
‣ Pre-crimped stainless steel fittings – built to withstand vibration and high-boost use
‣ CNC-machined 6061-T6 aluminum adapter fittings for precise sealing
‣ Copper crush washers included – leak-free installation
‣ Complete kit – no extra adapters or sourcing required
‣ Ideal for stock replacement, turbo longevity, or preventative maintenance

Upgrade your RX-7 FC’s turbo oil feed line before leaks or clogging become a costly failure. This braided kit ensures your HT18S-2S turbo receives reliable, filtered oil supply, protecting your rotary’s boost performance and extending turbo lifespan.

📦 Order today to keep your FC running strong with stable lubrication and peace of mind.
