A TYC CAF is designed to have the same or better filtration efficiency as the original equipment filter: its identical dust load capacity ensures the same amount of particulate-collecting power, while factory-correct level of pressure drop ensures proper air flow through the vehicle's cabin. Each TYC CAF also comes with step-by-step installation instructions for ease of replacement.
