Your car does not just automatically mix air and fuel haphazardly. It has what you call a mass air flow sensor (MAF) that measures air flow rate entering your car's engine through the plenum located near the intake manifold. The MAF converts the said flow of air into a voltage signal, which is then sent to the computer that determines the appropriate amount of fuel that needs to be injected into the cylinders. Because of this vital function, your mass air flow sensor needs to provide an accurate reading--all the time. If your engine is misfiring and your car has decreased in efficiency, then it is time for you to replace your MAF. Let us see if this Bosch mass air flow sensor will be a good replacement to bring your engine back to its original vigor.

We installed and tested this component on a BMW M5 and an Audi A3, and here is what we have to say:
- We were able to install this sensitive piece of hardware on the M5 and the A3 without any considerable difficulty; however, we needed to be really careful to prevent damaging the MAF. The process only required the removal of the fasteners, the orienting of the component, and the refastening of the screws and the wiring harness. Installation only took a good ten minutes for each car.
- When we ran the five-year-old M5 for half an hour, the problems with stalling and low gas mileage were unnoticeable. The new mass air flow sensor obviously did its job of supplying the right air-flow data to the computer, which resulted to the car's better performance.
- Previously, the A3 had an intermittent signal from the check engine light. But after the installation and the drive, the light never came on and the error code for the sensor did not register.
- The product packaging for the M5 MAF did not indicate that the component needed a five-star Torx Key and five-star Torx screws. We only found out that we needed this when we saw the mounting holes of the MAF.
- With Bosch claiming that this product is good, the two years of limited warranty is still not impressive compared with the lifetime limited warranty provided by other competitors.
Based from the test, this product was able to improve the performance of the M5 and the A3. This mass air flow sensor has a good mid-range price, and the warranty provided is not that bad at all. We also checked online reports, and they generally have a positive tone. Buying this component will surely be worth your time and money.
