Bosch P9307 - Oil Filter Car

Bosch P9307 – Premium Oil Filter for Modern Engines

The Bosch P9307 oil filter is engineered to deliver exceptional protection for a wide range of petrol and diesel engines. Designed with precision, it captures fine particles, contaminants, and sludge that can compromise engine performance and longevity. Its robust construction ensures reliable operation under high pressure and temperature conditions, making it a trusted choice for automotive enthusiasts and professional mechanics alike.

Key Features & Technical Highlights

• Advanced Filtration Media: Utilizes a multi-layered filter element that captures particles as small as 0.5 microns, ensuring the engine oil remains clean and free from harmful debris.
• High Flow Capacity: Maintains optimal oil flow rates, reducing pressure drop and preserving engine efficiency even during high-load driving.
• Durable Sealing: Equipped with a high-quality rubber gasket that prevents leaks and guarantees a tight seal during installation.
• Wide Compatibility: Fits a broad range of vehicles, including Citroën, Peugeot, Land Rover, Jaguar, and many others. The filter’s dimensions (Ø 89 mm, height 151 mm) match the specifications for models such as the Peugeot 407, Citroën C5/C6, and the Land Rover Discovery III.
• OEM Quality Assurance: Manufactured under Bosch’s stringent quality control processes, guaranteeing reliability and performance that meets or exceeds OEM standards.

Installation & Maintenance Guidelines

Installing the P9307 is straightforward, but following best practices ensures optimal performance:

1. Drain the Engine Oil: Before removal, allow the engine to cool and drain any residual oil.
2. Remove the Old Filter: Use a filter wrench to loosen and carefully detach the existing filter. Dispose of it responsibly.
3. Prepare the New Filter: Apply a thin layer of fresh oil to the rubber gasket to aid in sealing and reduce friction during installation.
4. Install the Filter: Hand-tighten the new filter until snug, then give an additional 1/4 turn with a wrench. Avoid overtightening to prevent gasket damage.
5. Refill Engine Oil: Refill with the manufacturer-recommended oil type and quantity.
6. Check for Leaks: After a short drive, inspect the filter area for any signs of oil leakage.

For optimal engine health, replace the filter every 10,000–15,000 km, or as specified in the vehicle’s service manual. Regular filter changes help maintain oil viscosity, reduce wear, and extend engine life.

Performance Benefits

• Enhanced Engine Protection: By trapping contaminants, the filter prevents abrasive wear on bearings, pistons, and camshafts.
• Improved Fuel Efficiency: Clean oil reduces friction, allowing the engine to operate more efficiently and potentially improving fuel economy.
• Reduced Emissions: Maintaining oil cleanliness helps the catalytic converter function effectively, contributing to lower exhaust emissions.
• Longevity: Consistent filtration reduces sludge buildup, preserving the engine’s internal components and extending overall lifespan.

Compatibility Matrix

The P9307 is engineered to fit a variety of models across multiple manufacturers. Below is an overview of key vehicle families and the corresponding model years that support this filter:

Why Choose Bosch?
