WIX Engine Oil Filter – 51288 (Cross Ref 035-115-591) The WIX 51288 is a premium spin-on oil filter engineered specifically for high-performance European engines. It serves as the direct cross-reference for the Volkswagen/Audi part number 035-115-591. While it is a primary engine oil filter for several inline-five cylinder Audi models, its heavy-duty construction makes it ideal for the high-pressure environments found in turbocharged systems. Maintaining clean oil is critical for the longevity of both the engine bearings and the turbocharger assembly. The 51288 features a high burst pressure strength and a precision-calibrated bypass valve, ensuring that your engine receives consistent oil flow even during cold starts or under extreme driving conditions. Detailed Vehicle Compatibility Audi 5000: 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988 Audi 5000 Quattro: 1986, 1987, 1988 Audi Quattro (Turbo): 1983, 1984 Nissan 1300: 1972, 1973 Product Highlights & Features Enhanced Media: Utilizes a specialty cellulose media blend that provides a 21-micron nominal rating, effectively removing microscopic debris that causes engine wear. High-Pressure Durability: Features a high burst pressure rating, making it ideal for the high-pressure oiling systems found in turbocharged European engines. Internal Bypass Valve: Includes a built-in 30 PSI relief valve to maintain oil circulation if the filter media becomes restricted, protecting the engine from oil starvation. Direct Fit: A direct replacement for OE part number 035-115-591, ensuring the correct thread pitch and gasket seating for Audi 5-cylinder blocks. Technical Specifications Part Number: 51288 Style: Spin-On Lube Filter Thread Size: 3/4-16 inch Height: 3.45 inches Outer Diameter: 2.92 inches Micron Rating: 21 Installation & Maintenance Tips Gasket Preparation: Always apply a small amount of fresh engine oil to the rubber gasket before installation. This ensures a proper seal and makes future removal much easier. Hand Tighten Only: Spin the filter on until the gasket makes contact, then tighten by hand another 3/4 to 1 full turn. Never use a filter wrench to tighten, as this can damage the gasket or threads. Check for Leaks: After an oil change, start the engine and let it idle for a few minutes. Visually inspect the base of the filter for any seepage before driving. Service Interval: For older Audi turbocharged engines, it is recommended to change this filter every 3,000 to 5,000 miles to prevent sludge buildup in the turbo supply lines. 51288 035115591
