Factory Bosch sensor for a 1987 Corvette. The sensor has been placed in a 3.5" Aluminum tube. It was on a running car with a 396" small block for 4 years, I just replaced the full EFI system. You will need to rescale the MAF tables in your tune, but this can handle way more airflow than the tiny plastic MAF. Includes the silicone fittings, IAC sensor, and clamps.
