You can them underneath the sensor when you’re cleaning it to catch the runoff when spraying MAF sensor cleaner. Optional, but nice to have for this project.

Shop towels are nice to have underneath the MAF sensor in order to catch the dirty runoff after cleaning. You mainly need a mass air flow sensor cleaner and some various tools to get access and remove the MAF sensor. A mass air flow sensor cleaner is required to safely clean the hot wire. Since the sensor on these vehicles utilizes an extremely delicate “hot wire”, used to measure air flow, it cannot be cleaned with regular cleaners or even brake cleaner. Over time, the MAF sensor can become dirty and require cleaning. Therefore, the MAF sensor plays a crucial role in determining the amount of air entering the engine. Such a function is instrumental in producing the proper mix of air and fuel for optimal engine performance. The Mass Air Flow (MAF) sensor is a device that is located at the air intake, which measures how much air is coming into the engine and then tells the vehicle how much fuel it needs to inject.
