Ensuring that measurement of air flow remains accurate and that the amount of fuel delivered to the combustion chamber matches up with the air input, regardless of how much you’ve boosted your Sierra, is the job of aftermarket 2014-2017 mass air meters. These meters often require an engine tune after installation to ensure they’re working properly, but they provide a huge advantage compared to the stock MAF. The factory instrument just can’t keep up with the higher pressures and flow rates, leading to poor combustion and even blow valves or explosions in the engine compartment, but these mass air meters keep everything humming along even if you’ve doubled the amount of cold air rushing into your engine’s interior. AmericanTrucks stocks air meters that get the job done – and are built for durability and accuracy, too.
