Installation Guide

1. Prepare: Warm up the engine to operating temperature, then shut off and allow it to cool slightly. Drain any residual oil from the filter housing if necessary.
2. Remove Old Filter: Unscrew the existing filter using a filter wrench or by hand. Be prepared for a small amount of oil spillage; use a rag or oil catch pan.
3. Inspect Housing: Check the rubber gasket and mounting surface for damage or residue. Clean with a solvent if needed.
4. Install New Filter: Place the new Bosch P3278 onto the housing, ensuring the gasket aligns correctly. Tighten by hand until snug, then give an additional ¾ turn with a wrench.
5. Check for Leaks: Start the engine and observe the filter area for any oil drips. If leaks appear, tighten slightly more or replace the gasket.

Performance Benefits

• Enhanced Engine Longevity: By trapping contaminants before they reach critical components, the filter reduces wear on bearings and pistons.
• Improved Fuel Efficiency: Clean oil flows more freely, reducing internal friction and allowing the engine to operate at peak efficiency.
• Consistent Oil Pressure: The dual‑valve system maintains steady pressure even under high load or rapid acceleration.
• Reduced Maintenance Costs: Fewer oil changes are required due to the filter’s extended service life, saving time and money over the vehicle’s lifespan.
