No Sputtering On My 1995 Nissan Pickup
Started to notice a little hesitation on my pickup. After the usual suspects were ruled out, plan B led me to the Mass Air Sensor. Easy to order, quick delivery, and perfect fit. She is running so quiet now, I think I can hear the neighbor’s Ford rust.

Very inaccurate
Wildly misreported airflow causing O2 sensors to show crazy lean conditions. Stayed in open loop. Swapped with a quality Delphi unit which fixed the problem. Not worth it to get one of these.

No More Code 2004 Yukon XL
At 1st I didn't think it worked because the check eng lamp was still on. But, when I rescanned there was a new code for an O2 sensor. MAF code was gone. Replaced the O2 sensor and the lamp went out. Time will tell if if has any durability. The OEM lasted 260k miles and 20 years. And, No, Im not expecting another 1/4 million miles or 20 more years. Maybe the gas milage will improve to 15mpg?

Save a lot of money!
If you can work a screwdriver or better yet a nut driver you can install this sensor. It fits perfectly. it will save you a ton of money. The least expensive sensor from a local parts supplier was $ 85 plus tax and the cost went up to $185. If you add in a mechanic you are probably looking at close to $200. I bought a code reader and the sensor for less than $90 and did the work myself. Took maybe 20 minutes.

Essentially plug and play. Easy to install and fixed my mass air flow code. Truck (2006 GMC 1500) runs and starts much smoother now.

Product seems to work, the dash light is no longer lit and the engine is running smoother than before as well as not running as rich. Haven't put any miles on it though. I was a little tight to get into the factory air hose but does fit nicely.

On initial installation, the product seems to be working properly. I may update this review in the future especially if I have problems with it in the near future.

Not great quality! Lasted about 3weeks and right back to hard 1-2 shift. Unplugged it plugged it back in and worked for a few days then back to throwing code.
