It delivers reliable lubrication, protects the engine from wear, and ensures optimal fuel economy by maintaining clean oil flow.

Key Features

• Advanced Filtration: The filter cartridge incorporates a multi‑layer media system that captures fine particles, soot, and metallic debris down to micrometer sizes. This protects pistons, bearings, and camshafts from abrasive wear.
• Durable Construction: Made with high‑quality polypropylene housing and reinforced rubber seals, the filter resists cracking under high temperatures and pressure variations typical in modern engines.
• Easy Installation: The design includes a quick‑release gasket system that allows for rapid removal and replacement without special tools. This is ideal for both professional mechanics and DIY enthusiasts.
• Compatibility Range: Engine codes such as STC2180, 5650303, 650302, 11422243359, and many others are supported. The filter fits models from the early 1990s to recent years, covering a broad spectrum of vehicle generations.
• OEM Quality: As an original equipment manufacturer part, it meets or exceeds Bosch’s stringent performance standards, ensuring long‑term reliability and engine protection.

Technical Specifications

Installation Guide

1. Prepare the Vehicle: Warm up the engine to operating temperature, then turn it off. Allow the oil to drain slightly for easier removal of the old filter.
2. Locate the Filter: The P9123 is typically positioned near the bottom of the engine block or on the side of the crankcase.
3. Remove Old Filter: Use a filter wrench or hand if the design allows. Carefully drain any remaining oil that may spill during removal.
4. Install New Filter: Place the new P9123 onto the mounting surface, ensuring the gasket aligns correctly. Tighten by hand until snug, then give an additional quarter turn with a wrench to secure it without over‑tightening.
5. Check for Leaks: Start the engine and observe the filter area for any oil seepage. If leaks appear, re‑tighten slightly or replace the gasket if damaged.

Maintenance Tips

• Replace the filter at every oil change interval recommended by the vehicle manufacturer.
• Avoid using a filter with a different size or material, as it may compromise engine protection.
• Inspect the gasket for wear before each replacement; a damaged seal can lead to oil leaks and reduced filtration efficiency.
