Mass Air Flow Sensor Replaces 10393948

Working great so far, fit like a glove

2012 Avalanche, with rich bank codes, rough idle on cold start, and loss of power. Also engine not running correctly can trigger ABS and stabilitrac failure. Immediately noticed a much better idle and power restored on acceleration. Stopping idle remains strong now, where before RPMs would dip and flutter. At a quarter of the price of a local parts shop, this isn't bad at all. Unless this review is updated, it's still working well. Super simple install, you just need a Torx bit for 2 screws. Comparing the Delco i removed the interior filaments and resistor LOOKS different, but wow..truck sure is running great now, and one small part solved SO many issues. No more check engine light for lean/rich banks. Great value!!

Works for me. Fixed the error code

Fixed fuel and air codes works great

fit my silverado perfectly.... cheaper that the auto parts store

Sadly to say that the sensor didn't work, my 2012 cadillac escalade just kept stopping once i installed the sensor, this product may be good but the one i received was no good, i had to buy one at Auto zone to actually drive my vehicle. Im not saying it's a bad brand just my experience was not meet, and resived a faulty unit.

Part store gave me incorrect information on scanner

Works as intended

It does the job but it's not perfect

Got the truck perfectly

Worked as intended

This item was well manufactured and properly packaged. My only complaint is with Amazon. They won't ship to my town with many items and it seems like more and more items come up with "doesn't deliver to this address". I have an alternate address but I need to drive 90 km to get it. Basically makes the item more expensive than using alternative suppliers like Rock Auto.
