Best Mass Air Flow Sensors of 2026

"When I installed this sensor, the fit was perfect and it immediately cleared my truck’s error codes.

As soon as my husband swapped it in, our truck was back on the road and running smoothly."

"My car wouldn’t start at all until I got this part. Now it runs perfectly. I really appreciate that it was so simple to install and fixed the problem right away."

"After my 2003 Camry LE threw a P0171 code, I realized my old eBay sensor was likely a counterfeit.

For the price, it’s a fantastic and reliable replacement—highly recommend it!"

"I installed it on my 1999 4Runner. While the sensor works well and installation was straightforward, the included O-ring was too large, so I had to reuse my old one. Other than that, it fits and functions as expected."

"I used this on my car's MAF sensor and noticed better engine smoothness and responsiveness. The cleaner is straightforward to use and dries quickly, making maintenance easy. I highly recommend it for keeping your engine in top shape."

"The part fit perfectly and has been working well for a few days now. No problems so far—if anything changes, I'll update, but right now, I think it deserves four stars because it does the job."

"For my 2008 Ford Escape Hybrid, this aftermarket MAF sensor was a nightmare. I kept getting 'Stop Safely Now' errors and even my mechanic thought my vehicle computer was bad. Turns out, the sensor itself was the problem—putting in a different one fixed everything. I would not recommend this for my car."

"I returned the product over two weeks ago, and I'm still waiting on my refund. Why the delay? I just want my money back."

"After replacing the sensor with a genuine GM part, the P0097 code on my Tahoe disappeared and the check engine light went off. I checked with my OBD2 reader to confirm. I always stick to GM or AC Delco for reliability—aftermarket just doesn't compare."

"On my 2015 Cadillac SRX, I was dealing with a rough idle that even the dealership couldn't diagnose. Swapping out the MAF sensor completely fixed the problem at a much better price than any local parts store."

"The installation was straightforward, and the product came in a sealed GM bag. After replacing the sensor on my '15 Tahoe, the intermittent IAT code disappeared permanently after several failed attempts at cleaning the original."

"After using a cheaper alternative, I switched to the GM Delco replacement and immediately noticed a difference—engine ran smoothly, no more chugging or rough idle, and the check engine light disappeared. Lesson learned: don't skimp on quality auto parts."

"After installing this on my 2004 Silverado 5.3L, the error code disappeared and hasn't returned. It was a good deal, came well-packaged, and was hassle-free. I’m holding back one star only because I want to see how it holds up over time, but for now, I’m satisfied!"

"Unfortunately, the sensor stopped working properly within a month on my truck and the same error code came back. My mechanic even called it 'garbage.' I wish it had lasted longer."

"After checking out some online forums, I turned to Amazon for the meter sensor and was happy to see car-specific details clearly listed. Reading reviews from others who’d faced similar problems made me confident in my purchase. The part showed up in under 48 hours, fit my vehicle perfectly, and was installed in about 10 minutes. Great price and exactly as described."

The sensor fits perfectly and feels well-made—definitely not a flimsy aftermarket part. Great value and reliable performance so far."

"I was hesitant because of some negative reviews, but my experience was positive. The sensor arrived brand new and packaged properly. Swapping it in took just 15 minutes, and it eliminated my P0101 code. After clearing the stored codes, my truck passed emissions testing without any issues. I would recommend this part to anyone facing similar problems."

"My 2000 GMC was showing persistent lean codes and unstable fuel trims. After confirming my old MAF was likely the issue, I chose this replacement based on solid reviews. Now, my truck runs super smooth and fuel trims are nearly perfect. It’s made a noticeable difference and resolved the codes I was dealing with."
