Nissan Skyline R32 R33 R34 GTR Idle Air Control/ACC Valve to Plenum Hose RB26DETT

Maintain the factory performance and reliability of your RB26DETT-powered Nissan Skyline R32, R33, or R34 GTR with Terra Firma Automotive’s New Genuine Idle Air Control (IAC) Valve to Plenum Hose. Also referred to as the Auxiliary Air Control (AAC) hose, this molded elbow connects the IAC valve to the intake plenum, delivering precise airflow at idle and during cold starts. As an essential part of your engine’s vacuum and idle control system, a damaged or degraded hose can result in vacuum leaks, poor idle, stalling, or inconsistent drivability.

This OEM hose is molded to exact RB26DETT specifications, offering the correct internal diameter, bend radius, and durability to handle the heat and pressure of a turbocharged engine bay. Unlike aftermarket or improvised alternatives, it installs with zero modification and ensures a secure, leak-free seal between your throttle body and intake manifold equalizer chamber.

Over time, the original hose becomes brittle, cracked, or shrunken—especially in high-mileage or tuned applications. Replacing it with a genuine Nissan part restores your Skyline's smooth idle and precise air/fuel balance, especially important for GTRs operating under demanding conditions.

Terra Firma Automotive is your trusted source for rare and hard-to-find OEM Nissan components. Our global network ensures access to authentic parts, including this increasingly difficult-to-source air control hose. Don’t compromise on performance—choose genuine Nissan quality and secure the longevity of your RB26DETT today. Order now and keep your GTR running like it was built to.
