Detailed Description

Protec 184 is an engine oil filter for drivers who service vehicles on traditional 3,000 to 5,000 mile oil change intervals. It uses enhanced cellulose filter media to capture contaminants from conventional motor oil while maintaining steady flow rates in everyday driving conditions. Laboratory performance data lists 95% efficiency at 29 microns and a burst pressure rating of 345, supporting routine engine protection in compatible applications.

This part cross-references Wix 51191 and FRAM PH19A for the same application. It is a direct-fit style filter for many older Audi and Volkswagen models, including Audi A4, Audi A6, and Volkswagen Passat applications that use a 3/4-16 spin-on oil filter.

What It Helps Address

  • Oil contamination from normal engine wear
  • Reduced oil retention after engine shutdown
  • Restricted oil flow during cold starts
  • Routine maintenance needs for 3,000 to 5,000 mile service intervals
  • Filtration service on older Audi and Volkswagen engines
