DENSO 260340-0580 – Oil Filter

Approvals and Standards OEM Standard: This filter is built to meet or exceed the original equipment specifications for the Toyota and Subaru models it is designed for. Denso is a primary OEM supplier for Toyota. ISO 4548-12: Likely tested to meet international standards for oil filter performance, including efficiency, capacity, and burst strength. Technical Highlights & Features Advanced Filter Media: Uses a synthetic blend media designed to trap contaminants efficiently while maintaining optimal oil flow and low restriction. Anti-Drain Back Valve: Features a high-quality silicone anti-drain back valve. This prevents oil from draining out of the filter when the engine is off, ensuring immediate oil pressure to critical engine components upon startup and reducing dry-start wear. Bypass Valve: Includes a robust internal relief valve that opens to allow oil to bypass the filter element if it becomes clogged or the oil is too cold and viscous. This failsafe ensures the engine still receives lubrication, even if the filter is blocked. Durable Construction: Features a sturdy steel base plate and canister, with a textured grip for easier installation and removal.
