The NISMO 16554-RSR46 R-Tune Air Cleaner Duct is a high-performance intake duct upgrade engineered specifically for the Nissan Skyline R34 GT-R. Developed as part of NISMO’s legendary R-Tune performance program, this duct is designed to reduce compressor intake restriction and improve airflow efficiency to the RB26DETT engine under high-load conditions.
By optimizing the air path leading into the factory air cleaner assembly, the R-Tune duct helps reduce intake pressure losses during peak boost operation while maintaining OEM-style fitment and drivability. Installation is straightforward and integrates with compatible factory and NISMO intake configurations without requiring ECU recalibration for street use.
Constructed from lightweight FRP material, this genuine NISMO component is an ideal upgrade for restoration-quality builds, street performance applications, or complete R-Tune-inspired engine bay setups.
