Show original supplier description
The NISMO Meter-Air Flow (B2680-RHR40) is a precision-engineered air flow meter offered as a faithful reproduction of the original Nissan genuine part (B2680-05U00). This essential engine management component is crucial for the RB26DETT engine across three generations of the legendary Skyline GT-R. Specifically designed for the Nissan Skyline GT-R (BNR32) from August 1989 onward, the Nissan Skyline GT-R (BCNR33) from January 1995 onward, and the Nissan Skyline GT-R (BNR34) from January 1999 onward, this air flow meter accurately measures the volume of air entering the engine. This data is vital for the ECU to calculate correct fuel injection duration and ignition timing, ensuring optimal performance and engine operation. Manufactured as part of NISMO's genuine reproduction parts program, this meter meets OEM specifications with correct sensing elements, calibration, and connectors. It ensures proper fitment and function for your GT-R's engine management system, providing durable construction resistant to engine bay conditions. Two units are required per vehicle.
