Product Details

Pronto Standard Life PO257 is an engine oil filter for drivers maintaining older and late-model import vehicles that call for this size and thread specification. The enhanced cellulose media is paired with a 25-micron rating to help trap wear particles, while the anti-drain back valve supports oil retention between starts. This makes the PO257 a practical choice for routine maintenance on applications such as Audi A4, Volkswagen Passat, and Volkswagen Jetta, as well as select Nissan models.

This part cross-references Premium Guard PG257 and Baldwin B114 for the same application.

What It Helps Address

• Oil contamination from normal engine wear
• Dry-start conditions after the vehicle sits
• Restricted oil flow caused by a clogged filter
• Routine service needs on compatible Audi, Volkswagen, and Nissan engines
• Filter replacement for vehicles requiring a 3/4"-16UNF spin-on oil filter
