Warmers operate on a chemical reaction with air similar to rusting. The warmer ingredients are iron, water, cellulose, vermiculite, activated carbon and salt.

How mass air flow sensors work. The sensing element, whether itâs a hot wire or hot film, stays hotter than air that comes into the fuel injector by being electrically heated. The hot film MAF is set at 75Â°C hotter than incoming air, while the hot wire is at 100Â°C above. The air cools the element as it moves past.
