Keep intake-air readings accurate with the Standard Ignition Engine Intake Manifold Temperature Sensor / Intake Air Temperature Sensor (AX454). This sensor measures the temperature of the metered air entering the engine and signals the ECM, which uses that reading to fine-tune fuel delivery and ignition timing. It installs as a direct-fit OE replacement across a range of BMW applications, including the 2013-2017 BMW X3 [L4-2.0L] and X5 [L6-3.0L], 2014-2018 BMW 328D and 328D XDRIVE [L4-2.0L], 2014-2016 BMW 535D and 535D XDRIVE [L6-3.0L], 2014-2017 BMW I3 [All] and [L2-0.6L], and 2015 BMW 740LD XDRIVE [L6-3.0L].

  • Direct-fit OE replacement: engineered for proper fit, form, and function for straightforward installation.
  • Plug-in connection: a single oval female plug-in connector with two male blade terminals.
  • Built to endure: high-quality materials and extensive testing back reliable performance.
  • What's in the box: the sensor only — no wiring harness, mounting hardware, or mounting bracket included.

Finished in black. If a failed intake air temperature sensor is the cause of symptoms like rough idle, hard starting, or reduced fuel economy, replacing it with AX454 restores the ECM's accurate air-temperature input. Country of origin: Italy.
