Product Details

The Premium Guard Standard Life line focuses on routine service filtration for everyday engine maintenance. PG5401 is a direct-fit engine oil filter for many Audi A4, A4 Quattro, A6, A6 Quattro, Allroad Quattro, S4, RS4, Cabriolet, and Volkswagen Passat applications. It is also cross-referenced to Baldwin B1429 and FEL-PRO 61355 for the same application. Use PG5401 when servicing vehicles that call for a spin-on oil filter with this thread size, gasket profile, and bypass setting.

What This Oil Filter Helps Address

• Engine oil contamination from normal wear particles
• Oil drain-back after shutdown that can delay lubrication on start-up
• Restricted oil flow caused by a loaded filter element
• Pressure spikes that require a bypass relief valve
• Routine maintenance needs on Audi and Volkswagen oil service intervals

Verify the thread size, gasket dimensions, and filter height against the original filter before installation. Replace the filter during each oil service, lubricate the gasket before tightening, and follow the vehicle manufacturer’s torque procedure. Confirm the application on 1995-2006 Audi A4, A4 Quattro, A6, A6 Quattro, Allroad Quattro, S4, RS4, Cabriolet, and 1998-2005 Volkswagen Passat models, including the 2001 Passat with oil cooler notes where listed.
