WIX oil filters have a full metal base plate for superior strength at the double seal. They also feature a silicone anti-drainback valve that stays flexible in extreme temperatures. This improves oil flow and keeps oil in the filter to prevent dry starts.
WIX oil filters use an up-front by-pass valve. This design is superior to top-mounted valves because it helps to keep oil from washing past dirty media and entering the engine. The glass-enhanced media in WIX oil filters offers greater efficiency, capturing more 10 to 12 micron sized particles than other cellulose/synthetic blend medias. They also have a coil steel spring to ensure internal filter parts are sealed properly.
