This MAF sensor is used with LS1, LS6, LS2, and LS3 engines. With calibration adjustments to the MAF frequency table in the PCM, this MAF can replace the 3 wire LT1 and LS1 MAF sensor. The intake air temperature sensor is integrated into this MAF sensor. *Unlike the SLP 85mm conversion, this will require PCM calibration*. Available with or without plug and play harness adapter for your 1997-2004 Corvette, F-body and GTO.
