Does Your Air Box Need Cleaning?
By Matthew Wright, About.com Guide May 5, 2011
Gunk is the enemy of your engine both inside and out. Your air filter catches lots of dust and larger particles that could potentially harm your engine, and you replace your air filter when it's dirty. But is that enough? The roads are unleashing an unending barrage of sticky stuff. Some of that is being sucked into your air filter housing, or air box. As this gunk builds up, it can adversely affect your car's performance. If you've never cleaned your air box, now's the time!
