The 10 Best Mass Air Flow Sensors
This wiki has been updated 11 times since it was first published in November of 2018. The MAF sensor is an integral component in modern cars and trucks that is used to determine the amount of air entering the engine. The engine then adjusts the amount of fuel injected into the manifold, which increases efficiency. Our selection will help you navigate the auto parts landscape, whether you are looking for a simple replacement or a performance upgrade. When users buy our independently chosen editorial picks, we may earn commissions to help fund the Wiki. Skip to the best mass air flow sensor on Amazon.

When choosing the best mass air flow sensor it is important to consider that what counts as the best varies by needs. You may be trying to simply replace a faulty part or instead you may be looking to make some performance upgrades to your engine. As far as replacement, the best and most cost-effective options will be original equipment parts provided by brands like Bosch, Denso, Delphi, and AC Delco.
Performance upgrades will vary depending on the extent to which you are committed to upgrades. There are the plug-and-play options like the Jet Performance 69180 and the Granatelli 350301 that require no additional modifications. We have chosen these as the best because they offer considerable horsepower and throttle response upgrades with the least amount of commitment.
There are also the BBK 8004 and the SCT Performance BA3000 that require matching with appropriate aftermarket intake systems and possibly larger injectors along with tuning the engine control modules. These offer the greatest amount of performance gains but require the most additional matching upgrades. When considering the options, something to keep in mind is that upgrades in air intake capacity must have corresponding upgrades to the flow of mass across the entire engine. Upgrading the diameter of air intake does little but create a choke point downstream at the exhaust if the exhaust ports are too small move the air being drawn by the intake.
Any in-depth engine modifications should be performed by trained automotive technicians to avoid personal injury or damage to the engine. The BBK 8004 is not CARB compliant and therefore not street legal in California - it can, however, be used on track cars.
