It uses a radial seal design that creates a leak-resistant connection to the air intake housing, even under rough vibration. The filter is constructed with high-efficiency cellulose media and a corrosion-resistant coated steel liner to trap dirt and debris before they enter your engine, protecting cylinders and components from premature wear. Replace this primary filter according to your engine manufacturer's intervals, and it is often paired with a Donaldson P532504 safety (inner) filter for complete system protection.
