It is likely a carbon filter, which means it is made of activated carbon and is used to remove impurities and contaminants from the air inside a vehicle. The "Sp" in the product name may stand for "sport," indicating that it is a high-performance filter. The 20mm designation probably refers to the size of the filter, which may be 20 millimeters in diameter.
