99+ MAF Sensor Sonic-Cruze In the first testOEM Replacement MAF sensor. This is a genuine Hitachi sensor. There are many reman or offbrand sensors on the market that do not perform as well as stock and can cause tuning fueling issues. Over time the sensor can get dirty and read low. Often a lean condition or 171 code can result. This works on 1999 and newer series 2 3800 only, does not fit 2004+ Grand Prix.
