Perhaps the biggest competitors in the market of oil filters for Ford Focus are brands MANN and FRAM. Consider a direct comparison of popular models Fram PH3614 vs Mann W7015, that fit to Duratec Petrol engines.
The first significant difference between these filters is the appearance. All FRAM filters are equipped with a special textured coating, which allows you to easily unscrew and twist them on the engine. The filters of MANN are painted in glossy paint, which makes it difficult for them to untwist their hands, soiled in oil.
Cut open oil filter and inspect
- After the cutting open of the body visually it seemed that the filter element in W 7015 bigger, because the fact that Fram inaccurately packed the paper.
- The thread is normally cut on both filters, which should not cause problems with unscrewing and twisting on the engine.
- The anti-drainback valve is fundamentally different. The MANN filters have a more elastic material than the FRAM. The bypass valve is also arranged in diverse ways, but in absolutely working condition on both products.
- The area of the filter paper after opening and measurement was 632 square centimeters in FRAM against 642 from MANN. The thickness of the paper is almost identical.
Both oil filters have dense material and almost similar characteristics, designed to operate up to 5000 miles. The quality of the MANN W 7015 manufacturing is slightly higher, which makes its choice preferable, despite the appearance of Fram PH3614.
