Pronto PO4476 Engine Oil Filter

Pronto PO4476 Engine Oil Filter

The Pronto PO4476 is a spin-on engine oil filter built for Toyota, Lexus, and select Suzuki applications that call for a 3/4"-16 UNF-2B thread and compact 3.01-inch height. It uses enhanced cellulose media, a 25-micron rating, and an anti-drain back valve to support clean oil flow at startup.

Standard Life Line Details

Pronto Standard Life filters are built for straightforward maintenance intervals and broad OE-style coverage. The PO4476 follows that approach with a compact canister design, enhanced cellulose media, and sealing dimensions that match many Toyota and Lexus oil filter applications.

What This Oil Filter Helps Address

• Routine maintenance needs on Toyota, Lexus, and Suzuki engines

Installation Notes and Tips

Verify the engine’s required thread size, gasket dimensions, and filter height before installation. The PO4476 is a spin-on filter, so the sealing surface should be clean and the gasket should be lightly lubricated with fresh engine oil before tightening to the manufacturer’s service specification. Confirm fitment for the exact trim and engine configuration on vehicles such as Toyota Camry, Toyota Corolla, Lexus RX350, and Toyota RAV4.

Quality Assurance

This filter is built with enhanced cellulose media, an anti-drain back valve, and an NBR gasket to support consistent service performance. Pronto’s Standard Life line is aimed at dependable replacement filtration for everyday maintenance across confirmed applications.
