Delphi AF10043 Mass Air Flow Sensor

The box arrived with the Delphi part number. You open it to not find any Delphi markings or stamped part numbers. Just a big made in China sticker. We will see how long it lasts. Buyer beware.

Doesn’t look legit to me. No part number, no Delphi tag, fishy. Sending back! Make sure you don’t open the plastic bag, I look through the cheap bubble wrap and could tell it’s fake. Update: I ordered from a “rock” solid auto parts store and the exact same part showed up. No Delphi tag like the pics. Exact same box. So I guess it’s legit? Who knows for sure I guess.

Great quality product. My check engine light no longer come on. Perfect replacement for LS2 engine in a 2006 GTO. I also noticed a difference in the way my car performs and responds now.

This is an OEM Delphi replacement MAF. You can pay less for the Chinese garbage and be frustrated when 80% of them dont work or fail early, or spend a bit more and simply solve your problem. I hesitated to even call my original part bad... Id get a code and check engine light maybe once a month and it ran fine otherwise. Replaced with this new Delphi part, and no more codes in months. My original factory part was also Delphi, and lasted 250,000 miles. I expect this will as well... Which makes it a better value that the cheap ones that seem to last a week or a month if they work at all.

Fast shipping great price

The service engine light came on and I couldn’t get it to go off despite several troubleshooting attempts. When I went to replace this sensor I discovered it was exactly the same as the original GM part. I paid nearly half for the part than I would have through a local auto parts store and, so far, I think I solved my problem.

Check engine code for blocked air flow. Air filter new, so not that. Replaced flow sensor, remove battery ground to clear out code, back in business in 20 minutes. $200 fix at a dealer.

I was receiving intermittent error code P0101 MAF Circuit Range/Performance. I tried to clean the original using MAF cleaner. That helped but I continued to receive the OBD error code occasionally. This replacement solved that problem. I have better idle, better acceleration, smoother cruising, and better MPG. Fit my 2003 Suburban 2500 8.1L perfectly. Only a slight difference in appearance from original but it functions very nicely. Electrical connections are identical and located in the same place.

Delphi made the MAF sensor for gm trucks. Save yourself a headache and buy it here. Ac delco sells for about $30 more, but has a Delphi sensor in the box. Only trust oem for sensor replacement.

This was identical to the sensor that was already installed on our 2006 Chevy Tahoe. Installed it and the check engine light turned off after probably 15 minutes of the car running. We had a mechanic check for the vacuum leaks and make sure the exhaust manifolds werent leaking. He said this was the next step and quoted us $300. We have a K&N filter so we will see if the oil causes any issues but I havent oiled it since we put it in.
