Restore the precision and reliability of your Nissan Skyline R32 GT‑R’s auxiliary air system with the Samco Sport TCS37/V Auxiliary Air Hose Kit. This set replaces all hoses associated with the RB26DETT’s auxiliary air circuit — a system essential for clean cold starts, proper idle stability, and factory emissions functionality.

After more than 30 years of heat cycles, the original rubber lines in the auxiliary air system often become brittle, cracked, or internally swollen, leading to vacuum leaks, rough idle, or inconsistent air‑pump operation. Samco Sport’s multi‑layer silicone hoses provide a modern, long‑life solution engineered to outperform the factory components in both durability and thermal resilience.

What the TCS37/V kit replaces:

• All auxiliary air system hoses connected to the air‑pump circuit
• Vacuum and pressure hoses feeding the auxiliary air control components
• OE rubber lines prone to cracking, collapsing, or leaking under heat

Because the auxiliary air system relies heavily on airtight vacuum routing, even the smallest leak can cause noticeable drivability issues. Upgrading to silicone ensures stable, consistent airflow and restores the factory‑intended operation of the RB26’s emissions support system.

Key enthusiast benefits:

• High‑quality, multi‑layer silicone construction for superior heat and vacuum resistance
• Restores proper auxiliary air flow for smooth cold starts and cleaner idle behavior
• Long‑term reliability with reduced risk of vacuum leaks or hose collapse
• Precise OE‑matched routing for an easy, factory‑correct installation

Colour options:

• Available in multiple colour variations to match the rest of your engine bay
• Includes a Classic Black option for those seeking an OE‑style appearance with modern silicone durability

If you’re refreshing or troubleshooting your R32’s vacuum and emissions systems, the TCS37/V Auxiliary Air Hose Kit is a smart, targeted upgrade that eliminates aging rubber from one of the GT‑R’s most leak‑sensitive circuits. A cleaner idle, smoother startup, and long‑term reliability — all wrapped in Samco Sport quality — make this a must‑have component for any RB26 restoration or performance build.
