85mm MAF 3 Wire To 5 Wire Adapter 108100
When converting your LT1 or LS1 from the factory 3 wire MAF to an 85mm 5 wire MAF, you will need this MAF adapter to attach to the factory harness. This will allow the built in IAT sensor in the 85mm MAF to be functional in place of the detached oem factory sensor.
This will give you a nice clean installation and not require you to drill a hole in your air lid to retain the factory IAT sensor.
