Bosch P9139 - Oil Filter Car

Bosch P9139 – Premium Oil Filter for Automotive Engines

The Bosch P9139 oil filter is engineered to deliver superior protection and performance for a wide range of high‑performance vehicles, including BMW, Land Rover, Opel, Vauxhall, and Omega models. Designed with Bosch’s renowned precision manufacturing, this filter ensures optimal engine longevity by effectively removing contaminants from the motor oil.

Key Features

• High‑Efficiency Filtration: Utilizes a multi‑layer media system that captures fine particles and metallic debris down to sub‑micron levels, safeguarding pistons, bearings, and camshafts.
• Robust Construction: Made from durable synthetic fibers and reinforced with a high‑temperature seal, the filter withstands extreme operating conditions without compromising filtration integrity.
• Low Pressure Drop: Engineered to maintain optimal oil flow, reducing engine load and preserving fuel efficiency while still delivering maximum protection.
• Universal Fitment: Compatible with a broad range of models such as BMW 3‑Series (E36/E39), 5‑Series (E34/E38), Land Rover Range Rover II, Opel Omega B, Vauxhall Omega, and many others. The filter’s dimensions (outer diameter 83 mm, height 160 mm) match the OEM specifications for these vehicles.
• Easy Installation: Features a pre‑sealed gasket that eliminates the need for additional sealing compounds or oil drain steps during replacement.

Technical Specifications

Installation Guide

1. Preparation: Warm the engine to operating temperature. Drain a small amount of oil from the dipstick tube to prevent spillage during filter removal.
2. Remove Old Filter: Unscrew the existing filter using an appropriate wrench or hand tool. Allow residual oil to drain into a container.
3. Install New Filter: Place the Bosch P9139 onto the filter housing, ensuring the gasket aligns correctly. Tighten by hand until snug, then give an additional quarter turn with the wrench.
4. Re‑fill Oil: Refill the engine with the recommended oil type and quantity. Check for leaks around the filter seal.
5. Check Performance: Start the engine and let it reach normal operating temperature. Verify that oil pressure remains within manufacturer specifications.

Benefits to Vehicle Owners

• Extended Engine Life: By trapping contaminants before they can cause wear, the filter helps maintain optimal engine performance over many thousands of miles.
• Improved Fuel Economy: The low pressure drop reduces parasitic drag on the oil pump, contributing to better fuel efficiency.
• Consistent Oil Quality: Regular replacement ensures that the motor oil remains clean, preserving its lubricating properties and preventing sludge buildup.
• Reliability Across Models: The filter’s universal fitment means owners of multiple vehicle brands can rely on a single product for all their maintenance needs.

Why Bosch?

Bosch is synonymous with automotive excellence. Their rigorous quality control, extensive research into filtration media, and commitment to durability make the P9139 an industry standard for oil filter performance. Whether you drive a high‑performance sports car or a rugged off‑road vehicle, this filter delivers the protection your engine deserves.

Maintenance Tips

• Replace the filter every 10,000 km (or as recommended by the vehicle manufacturer) to ensure continuous protection.
• Avoid using low‑quality oils that may contain higher levels of contaminants; this will further extend the life of the filter.
• Inspect the filter housing for cracks or damage before installation. A damaged housing can compromise seal integrity.
