This is most commonly used in either Northstar throttle body conversions in L67 powered vehicles, or 04+ Grand Prix' with the L32 engine as an upgrade because the factory MAF sensor is only 75mm. This MAF will generally support up to around 380-400whp. A Mini AFC can be used along with it to support well over those #s.

This is not a simple plug and play product, the kit comes with the coupler/clamps to connect the MAF to the throttle body, but you will still need to find a way to connect the inlet side of the MAF sensor to the rest of your intake tube. The size and angle of your intake tube will have a huge effect on how the airflow passes the airflow element, it will require a LQ4 MAF chart to be inserted in the PCM file and possibly even custom tuning.

Series II: 97-03 Grand Prix, 97+ Regal, Monte Carlo, Impala, Bonneville, Park Ave.
Series III: 2004+ Grand Prix only model includes a different 5 to 5 wire MAF adaptor harness and does not include a MAF blockoff plate.

This item and all electrical items are non-returnable, please be aware of this before ordering.

Includes:

  • 85mm GM MAF sensor
  • MAF adapter harness
  • stainless MAF blockoff plate (for Series II only)
  • Silicone boot
  • 2 stainless hose clamps

Got to install with 4" fenderwell intake, afr were close after pasting the base numbers from a stock truck, if you do both the intake and maf swap increase the maximum airflow through the throttle body in the tune as well or you won't get 100% throttle till 3500-4krpm
