The maf sensor is original oem.
When I ordered another maf sensor from a different company through Amazon it failed in less than a week and I had to send it back,this one is the original oem part that came with my 2010 Malibu,so it was just installed today and from a cold start stand point(without having to press my accelerator)it started my engine right up with no issues (which is the main problem I was having with the original sensor)If I don't add to this review in the future then you can bet that this sensor worked for me.If I do however have any issues with it, I will return with another more negative review.But like I said this is an original oem maf sensor made in japan and so far it has fixed the check engine light and the rough idle with a no start condition I had previously.Thanks Amazon.

Reputable brand
Now this brand has been around for awhile . Functions great most of the time and have some of the better or best quality products for the price. Durability should be good but different car brands act a little different but so far have heard good things about this one. Time to try it out.

The Brand
This did the trick better gas mileage, shifts better, and more power the MAF rarely causes the check engine light to trip. Mine was 6 years old but the new one fixed it. Recommended!

Would not recommend
I've recently learned that it way better to buy these things at the local auto store. Got this and another similar product and no improve. Still read as error. When I got from the auto store, the error message went away. Not sure what that is about. Do not recommend.
