Description:
The WIX Spin-On Lube Oil Filter 51085 delivers reliable engine protection and consistent oil flow for Chrysler, Dodge, and Jeep vehicles (1991–2010), as well as Mitsubishi Eclipse (1995–1999) models. This filter is also commonly used in select Caterpillar, Freightliner, and other industrial equipment applications. Constructed with enhanced cellulose media, it efficiently removes contaminants to maintain clean oil and smooth engine operation. The anti-drain back valve prevents oil from draining during shutdown, reducing wear during startup, while the 8–11 PSI bypass valve ensures steady lubrication under restricted conditions. Built with a 340 PSI burst pressure rating, the WIX 51085 provides long-lasting durability and OEM-level performance across both automotive and heavy-duty uses.
