WIX  Accessories

Metal Free Fuel Filter Cartridge by WIX®. The fuel filter is often the forgotten filter. Yet the fuel put into diesel and off-road equipment, more often than not, contains contaminants such as dirt, rust, scale and water. These impurities can plug fuel injectors and carburetors, resulting in engine malfunction or deterioration. These contaminants often originate from dirty and rusty storage tanks, and as the vehicle ages, from corrosion within the fuel system components. All the more reason to invest in high-quality WIX fuel filters and to maintain them at recommended intervals.

The last few years' alternative fuels, such as biodiesel, have drawn considerable attention in the industry. When converting to a biodiesel blend, it’s important to remember that biodiesel has a “solvent” quality, which will result in the cleansing of the fuel system, and may subsequently clog the fuel filter. After the initial clean up of the fuel delivery system, fuel filter service intervals will return to normal under biodiesel utilization. Biodiesel also has a tendency to attract more water mixing with the fuel, increasing the need for proper fuel/water separation.

Limited Warranty

New car and equipment warranties remain in effect when WIX filters are used.

WIX Filtration Products warrants each WIX filter to be free from defects in material and workmanship during the period of service life recommended by the engine or equipment manufacturer.

If your WIX filter is found to be defective in material or workmanship during the period of service life recommended by the engine or equipment manufacturer, WIX Filtration Products will replace the defective filter with another WIX filter.
