TYC 800054C BMW Z4 Roadster Replacement Cabin Air Filter
Pollen, allergens, various fuel-based contaminants from the outside road environment all pass into and are filtered by your vehicle's Cabin Air Filter, or CAF. 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.
