Bosch 72271WS Workshop Spin-On Engine Oil Filter - F00E164424

The Bosch 72271WS (cross-reference: F00E164424) is a spin-on Workshop Engine Oil Filter engineered for professional installers and discerning DIYers who demand reliable engine protection. Utilizing Bosch's exclusive filter media technology, this canister-style filter captures up to 97.5% of harmful particles — including dirt, carbon deposits, and other contaminants — at 20 microns (per ISO 4548-12 testing on L3500).

Key Features:

• 97.5% filtration efficiency — screens harmful particles such as dirt and carbon deposits from engine oil
• 13-gram contaminant holding capacity — traps and retains harmful particles to prevent recirculation and engine wear
• Stronger steel baseplate and housing — resists warpage, leaks, and poor fit for a secure, reliable seal
• Silicone anti-drainback valve — retains oil in the filter when the engine is off, preventing dry starts and premature wear on startup
• High-lubricity synthetic rubber gasket — creates a tight, leak-free seal while allowing easy removal at oil change time
• Double-locked rolled seam canister — provides an additional layer of leak protection
• M20 x 1.5 thread size — direct spin-on fitment
• 200 PSI maximum burst pressure — built to withstand high-pressure engine environments
• Bypass relief valve included — protects the engine if the filter becomes restricted

The Bosch 72271WS Workshop Oil Filter is sold individually and is designed as a direct replacement for routine oil changes. Its cellulose filter media with nitrile gasket construction delivers dependable performance across normal service intervals.
