Your cart is empty.An ACDelco GM Original Equipment Mass Air Flow (MAF) Sensor is a key part of the engine management system, and is a GM-recommended replacement for your vehicle’s original component. The MAF sensor measures the amount of air entering the engine so that the engine control module can determine the amount of fuel to inject. This ensures the most efficient air/fuel mixture for the best fuel economy and power, while reducing harmful exhaust emissions. This original equipment mass air flow sensor has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

The new part has a different part number than the old stock part but was the exact same fit. I only buy AC Delco replacement parts for my vehicles and have never had any issues. It took like 5 minutes to switch the part out. Remove two torx screws, disconnect the harness from old part and attach the new one. Screw it back in place and DONE !

Good replacement for my 2011 Avalanche. The set screws down into the hard plastic tubing, so be careful not to strip out the threads cos it could affect a good seal. Not many other choices when you need one of these and a bad on will shut the engine down after it starts running roughly.I have a friend with the same truck, so we switched them in our trucks and my bad one did the same thing in his truck, started right up and engine died in 10-15 seconds; would not stay started!

This worked marvels for my 2012 Cadillac Escalade ESV Platinum Edition! It was super easy to install and an exceptional value for the price! My truck had a "few" codes before the Mass Flow Sensor was installed. Looks like it cleared them all because my truck passed the emissions test! It helped and works like a charm!

Hard to tell the difference my issues might be from the injectors but figured I try this first … good to have new parts in a 11 yr old tahoe

I opted to buy the DC Delco original part. Good decision looking at reviews on cheaper replacement party

Mass air flow sensor arrived next business day. Installation was pretty simple. Came in original box (AC Delco) highly recommend getting this part as OEM is best.

This thing sent my truck in a tizzy about 5 months after. I dont drive a ton but something never seemed right with this. live data was close but the obvious' never improved anything. fast forward a few months and this MAF failed entirely, after the truck started lean popping headed to work and adding 50% of ltft it turns out this was already dead. I question the validity of this being provided by GM. no one ive talked to at work can reciprocate this was offered by GM, got one from the dealer which is much better thus far. wish i could get my money back from this

Perfect replacement to a dirty or broken mass airflow sensor. This will get rid of many mass air flow sensor errors that your car might be showing an OBD2 code for. Easy to install.
