How do I know when to replace my Air cleaner?
A dirty air filter can cause reduced fuel economy, engine misfires, unusual engine sounds, or reduced horsepower. Most manufacturers recommend replacement every 15,000-30,000 miles, or more frequently in dusty conditions.
What tools do I need to replace a Air cleaner?
Tools needed: none for most vehicles (airbox clips open by hand); some require a flat-head screwdriver or T20 Torx. Difficulty: Easy DIY. Safety warning: Ensure the airbox is fully sealed after fitting -- an air leak downstream of the mass airflow sensor will cause running problems and potential fuel mixture faults.
