LQ4 MAF Sensor
This product is currently out of stock.
This is the popular "LQ4" Mass Air Flow Sensor. It is most commonly used in the Northstar throttle body conversion kit. It is popular because its range is slightly larger than stock and is a 3.75" clamp in style MAF, so it doesn't require a MAF pad. It is also used in our GM 85mm MAF Sensor kit.
This is used in very many factory GM applications.
New Delphi unit.
