While a lot of people tend to ignore them, air filters are a very important part of the internal combustion cycle (you know, Suck, Squeeze, Bang, and Blow). They have to strike a tricky balance, too- how do you stop dirt from ruining the air flow without ruining the air flow by yourself?
When the air flow is obstructed, your engine needs to work harder to make thousands of those mini-explosions going on inside your engine every minute. This results in both less power and lower fuel economy. So how do you make more power and get more fuel efficiency? Or, rather, how do you have more fun and save the planet at the same time?
Buy a better filter, like the ones made now by Green Filter USA. Unlike other filters, theirs uses a double cross-woven cotton material that helps the engine to breathe. They say they got 5.6% better gas mileage out of a V8 engine. And the best part is it’s washable and reusable, so you don’t kill trees or have to cough up an annuity every year. There’s no word yet on how long they last, but other washable filters are certified for at least 10 years.
