Detailed Description

Wix 51799XD is engineered for heavy-duty engine protection in medium- and heavy-duty trucks and other equipment that operate under severe conditions. The filter’s high-strength construction, superior sealing components, and high-capacity media are intended to support OEM oil and filter change intervals where the application calls for them. This part cross-references Fleetguard LF9026 and NAPA Gold Filters 1799XD for the same application.

Fitment includes 1990-2013 International and IC Corporation commercial platforms, including International 4300, 4400, 7400, 4700, 4900, 3800, 5500i, 5600i, 8100, 3000, 3000RE, 3200, 7300, 7500, 7600, and 7700, plus IC Corporation RE Commercial, RE School Bus, and RE Integrated applications. The Wix 51799XD part number is also used across extended-drain and manufacturer OE-recommended service intervals on many of these vehicles.

Common Uses
