INSIDE AN OIL FILTER????

Oil filter filtration efficiency is directly related to the total surface area of the filter media, which can be calculated by multiplying the number of pleats by the pleat length and height. In this analysis, the Purator 1 PL24651 oil filter demonstrates superior filtration capacity compared to the Motocraft FL820S, featuring 60 pleats (vs. 50) and 75 inches of media length (vs. 69 inches), resulting in approximately 168.75 square inches of filtration surface area compared to 69 square inches. This represents about 142% more filtration surface area at a significantly lower price point ($5 vs. $15), making it a more cost-effective option for consumers seeking enhanced oil filtration performance.
