The air filter housing (airbox) contains and supports the engine air filter element, channels incoming air across the filter media, and usually includes a temperature-controlled fresh/warm air intake flap. Cracks in the housing, a poorly seated lid, or a failed air intake duct allow unfiltered air to bypass the filter and enter the engine, causing accelerated bore and valve train wear. Replacement housings are available for most vehicles.
Airbox damage is often overlooked. Symptoms can mimic a faulty MAF sensor or intake air leak.
Airbox replacement is generally straightforward — it is usually retained by two or three bolts and a flexible intake duct.
