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.
