Match the right amount of fuel to the air your engine is actually breathing with the Beck/Arnley Mass Air Flow Sensor 158-1800. It installs as a direct-fit replacement across a wide range of Ford, Lincoln, and Land Rover applications — including the 2015-2023 Ford Mustang [V8-5.0L], 2016-2020 Ford Fusion [L4-2.5L], 2015-2019 Ford Transit-150/-250/-350 [L5-3.2L, V6-3.7L], and 2012-2017 Land Rover Range Rover Evoque [L4-2.0L]. See the Buyer's Guide tab for the full list of 29 applications.

A mass air flow sensor measures the mass of air entering the intake so the engine control module can meter the correct amount of fuel. If a failed MAF sensor is the cause of symptoms such as rough idle, hesitation, stalling, poor fuel economy, or a check engine light, this replaces it.

  • OE form, fit and function: matches the original equipment sensor's form, fit, and function.
  • Application-specific: built for your vehicle — check catalog data and confirm fit before ordering.
  • Diagnose first: also inspect the air intake system for vacuum leaks, dirty air filters, and damaged wires or connectors; professional diagnostics are recommended.
  • After install: consult a service manual, which may include a relearn or reset procedure.
