There is a great improvement in performance in driving. my range increased 20% for the same amount of fuel i use to fill. However i did changed all spark plug and cleaned the throttle and catalytic convertor. My old one doe work after i cleaned , but replacing with new made a big difference.

I own a 2003 Toyota Camry LE, and when the check engine light came on with the code P0171, I initially thought the issue wasn’t related to the Mass Air Flow (MAF) sensor. A couple of years ago, I had purchased a cheap, likely counterfeit DENSO MAF sensor from eBay, but after a detailed diagnosis at the dealership, it was confirmed that the sensor was faulty. Since DENSO is the OEM for Toyota parts, I realized that the eBay sensor wasn’t genuine, which explained the issue. I was hesitant to buy another non-OEM one, fearing it might also be a fake, but I decided to give this sensor a try after reading some positive reviews. Installed it in Nov 2024. The installation was simple since I had done it before, and I could immediately tell the difference. The car no longer struggled during acceleration, ~3 months and ~1000 miles later, the check engine light remains off. It even passed the emissions test last week! This sensor works flawlessly and is a much more affordable option compared to the expensive OEM parts. I highly recommend it to anyone looking for an affordable and reliable replacement for a faulty MAF sensor!"

Spectacular. I changed it and my 4runner looked like another vehicle. The failures are over and it became economical!

Excellent quality. Still working after a year and a half at a fraction of the price

Installed in a 1999 3rd Gen V6 4Runner. The New sensor seems to be working fine, but it did not correct my rough running engine problem as I had hoped. One problem with this product is that the O-ring is slightly too large, and the sensor would not fit into my car with this O-ring despite adding lube and lots of force. I had to use the old O-ring from the removed sensor to complete the install.
