7. Keep the Air Filter Clean
Imagine breathing through the straw that came on the side of a Capri Sun. Now try to run a marathon while aspirating through said tube. Chances are you’ll die before making it two blocks, three at most. It’s no different for your car.
Like a tiny plastic straw, dirty air filters restrict an engine’s ability to breath, robbing it of performance and potentially reducing economy. But don’t fret, there’s good news. These puppies are pretty cheap and they’re generally a snap to replace; oftentimes no tools are required. Go ahead; flip your mechanic the bird. This is one maintenance item you’ve got covered.
