The Mass Air Flow Sensor is a critical component of your vehicle's Engine Management System. Positioned between the Air Filter and Throttle Body, it plays a vital role in measuring the precise amount of air entering the engine. In many cases, it also includes the Intake Air Temperature Sensor (ATS).
With its precise measurements, the Mass Air Flow Sensor provides valuable input to the Engine Management Electronic Control Unit (ECU). This information, combined with data from other sensors, enables the ECU to determine the optimal Air/Fuel ratios, Ignition timing, and, on certain vehicles, transmission shifting.
Key Features and Benefits:
- Engine Performance Enhancement: By accurately measuring the air intake, the Mass Air Flow Sensor helps optimize engine performance, resulting in improved power and efficiency.
- Improved Fuel Economy: With the correct Air/Fuel ratios determined by the Mass Air Flow Sensor, your vehicle can achieve better fuel economy, saving you money at the pump.
- Enhanced Engine Management: The Mass Air Flow Sensor's signal is utilized by the Engine Management ECU to ensure precise air and fuel mixture, ignition timing, and transmission shifting for optimal performance.
- Reliable Sensor Technology: Crafted with advanced sensor technology, the Mass Air Flow Sensor provides accurate readings for consistent engine operation.
- Easy Installation: Designed for hassle-free installation, the Mass Air Flow Sensor seamlessly integrates into your vehicle's air intake system.
- Durability and Longevity: Built to withstand harsh operating conditions, the Mass Air Flow Sensor offers long-lasting performance and durability.
Upgrade your Engine Management System with the Mass Air Flow Sensor to unleash the full potential of your vehicle. Experience improved engine performance, enhanced fuel economy, and reliable engine management. Invest in the Mass Air Flow Sensor for a smoother, more efficient driving experience.

Packaging note: PAT products may be supplied in PAT Premium packaging instead of the manufacturer's original box.
PAT sources EFI and engine-management parts from established OE-type manufacturers and repackages some of them in Australia. The manufacturer inside can change between batches as supply changes — for example, a part once made by Hitachi may now come from Bosch. Every unit is an OE-type part from a recognised manufacturer.
Packaging: Manufacturers periodically update their packaging and labelling. You may receive the current or a previous design — the product, formulation and part number are unchanged.
Fitment (vehicle-specific products): Vehicle fitment is based on manufacturer and supplier catalogue data and is kept as accurate as possible, but vehicle catalogues are not perfect. Some models had more than one part fitted depending on build date, engine, or component size/variant, and parts on older vehicles may have been replaced with non-original or different-style components.
Before you buy, compare the product images with the part currently fitted to your vehicle — check shape, size, connectors and mounting points. If the part on your vehicle looks different, please contact us before purchasing. It is the buyer's responsibility to confirm the part suits their vehicle before purchasing.
Not sure? Message us with your vehicle's registration number and state (preferred), or full VIN/build details, and we'll do our best to confirm fitment before you buy.
Parts returned because they do not suit the vehicle, where the listing matches the manufacturer's catalogue, are treated as a change of mind and must be unused, uninstalled and in original packaging. Nothing in this notice affects your rights under the Australian Consumer Law.
