How to Clean a Vehicle’s Mass Air Flow Sensor (MAFS)

Reading time: 291 words, 1 page, about a minute plus 3:24 video.

It took me less than 10 minutes to clean my car’s MAFS using CRC SensorKleen and now it’s purring like a kitten. Watch the video for a demonstration.

I didn’t even know what an MAFS was until I read it on a discussion board about K & N air filters which I highly recommend for improving BOTH power & mileage.

I found by research and experience that increasing the efficiency of air flow into the engine throttle improves horsepower AND gives better mileage. It’s the only change you can make that improves both. Everything else you can do for either power or mileage is a trade-off.

Usually, a power increase uses more fuel, hence poorer mileage. On the other hand, an improvement in mileage (i.e. less fuel) results in less horsepower. Only increasing the efficiency of air flow improves both.

Paper air filters and factory air inductions are not efficient. One of the best ways to increase air flow is with a K & N air filter. A further step to increase air flow is using both a K & N air filter and a ‘cold air induction kit’ but an induction kit is fairly expensive.

Note: the downside of K & N air filters is they take a bit more work because, instead of discarding a paper air filter, the re-usable K & N’s must be cleaned, dried and re-oiled. On the other hand they have a lifetime warranty and the fuel savings more than pays for the extra expense of a K & N.

I calculated about a 6% improvement in city mileage and almost 10% on the highway but remember; every vehicle is different.

I have a bit of financial experience having invested in stocks in the 1960s & 70s, commodities in the 80s & commercial real estate in the 90s (I sold in 2005.) I'm back in stocks. I am appalled at our rapidly deteriorating global condition so I've written articles for family, friends & colleagues since 2007; warning them and doing my best to explain what's happening, what we can expect in the future and what you can do to prepare and mitigate the worst of the economic, social, political and nuclear fallout. As a public service in 2010 I decided to create a blog accessible to a larger number of people because I believe that knowledge not shared is wasted.
