Most modern EFI (electronically fuel injected) vehicles operate with the assistance of a device called a Mass Air Flow sensor, also known as an airflow meter. This sensor applies a constant voltage to a small wire, which sits in the intake system. The voltage applied heats this wire to known temperature, and as cool air flows past the wire, the wire is cooled. This, with the conjunction of clever mathematics can give the car's computer a good idea of how much oxygen is being accepted by the intake system, and adjust fuel mixtures accordingly.

However, as a vehicle is driven, it is common for a small layer of dust or oil to build on the sensor wire, insulating it from the airflow, potentially leading to under-fuelling at lower road speeds. Due to the sensitivity of the component, physically touching the sensor may lead to damage, whilst some cleaning products may leave a residue, potentially compounding the issue. That is where this CRC Mass Air Flow Sensor Cleaner can offer a brilliant solution.

CRC's Mass Air Flow Sensor Cleaner is supplied in a spray form, providing clean and directed spray patterns. Unlike other spray cleaners that might leave a film to prevent the build up of dust and grease, this CRC spray is engineered to penetrate and remove dust and dirt, without leaving any film or residue that could interfere with the operation of the sensor. This spray is also plastic safe, so it won't damage the sensor mount, or the sensor housing regardless of its construction.

So grab a can today, and make cleaning your Mass Air Flow sensor a part of your service routine. It is inexpensive, easy to do and can go a long way to improving your cars economy, lifespan and performance.
