Is your BMW acting up with rough idle, poor acceleration, or a check engine light?

It might be a dirty or faulty mass air flow (MAF) sensor.

This X AUTOHAUX replacement is a direct fit for a ton of BMW models from the early 2000s up to 2016—including the 1 Series E87, 3 Series E90/E92, 5 Series E60, 7 Series, X3, X5, and X6 (check the full list to confirm your exact model).

It has the OE number 13627788744, 4 pins, and is made from durable plastic and metal.

Replacing it can restore proper air-to-fuel ratio, improve engine performance, and maybe even boost fuel economy.

Installation is pretty straightforward—it's located near the air intake box—but make sure the engine is cool before you start.

Pro tip: after installing, you might need to clear the error code with a scanner for the check engine light to turn off.

Comes with just the sensor.
A solid, affordable fix instead of going to the dealer.
