Inspecting air filters is vital because they trap dust and fine particles from entering the engine. A clogged filter causes wear, power loss, and black smoke. Follow these simple inspection steps:
1. Remove the outer filter element and inspect dirt levels using compressed air blow-out.
2. Hold it up to light; if light passes through, the filter is clean. If no light passes through, replace the filter.
3. Inspect the inner safety filter; if dirt has penetrated the inner element, replace both filters immediately.
Regular air filter maintenance preserves engine health and fuel economy.
