The air mass meter is a critical component in today's modern vehicle. It is responsible for measuring the incoming air mass and feeding this as an electronic signal to the ECU. The ECU uses this information to calculate the exact amount of fuel and ignition timing required for the engine loading. This in turn ensures that optimum vehicle performance and emissions targets are achieved.
A faulty existing unit or poor quality replacement unit can have a severe impact on a vehicles performance and economy.
O.E quality sensors employ platinum sensor technology. Whilst many aftermarket alternatives use inferior technology and materials the SMP manufactured sensors use an in house designed platinum sensor element similar to that found in many O.E systems. This element has a proven record for long life and high performance.

Although quite simple in operation the SMPE produced air mass meter is an extremely complex component. The platinum element is held at a constant temperature of 380° C. The complex electronic circuitry ensures that this temperature is maintained regardless of the volume of air entering the inlet tract thus cooling the sensor. The ECU interprets the current draw required to maintain the temperature of the sensor and so provide the appropriate injector and ignition control.
All of our unit’s are individually 100% tested in preference to batch testing which often has a dire effect on end quality. Each unit is tested and electronically calibrated to its design specifications, achieving consistently repeatable results exactly matching OE performance.
The calibration utilises programmable technology and not the more common (cheaper) variable resistor, traditionally used in aftermarket mass meters which frequently go out of synch when subjected to engine vibration.
All of our UK manufactured mass air flow meters have our logo etched on to them and they are
electronic coded with a serial number to allow full traceability. Each unit has an individual test
certificate included as a quality assurance
Our manufacturing and test facilities have been designed in house to our own custom specification, every step of the way has had quality stamped on it.
