BOSCH Oil Filter 0451103139 [ P 3139 ]

The job of the oil filter is to protect the engine against impurities in the oil such as dust, metal particles, combustion residue or soot particles.

With modern engines it is vital that replacement oil filters are made to the same high standards that the vehicle manufacturer specifies. Filters not made to this specification could lead to poor engine performance and damage.

Bosch have a comprehensive range of oil filters covering most vehicles on the road today. So make sure you insist on Bosch oil filters when replacing them in your car.

• Premature engine wear, which can even lead to engine damage
• Reduced engine power
• Increased oil consumption
• Oil leaks

On short-distance trips and in stop-and-go traffic, the oil and the oil filters should be changed more often than the replacement intervals specified by the vehicle manufacturer. Frequent cold starts lead to more condensation and a fuel surplus in the combustion mixture. This means:

• Unburnt hydrocarbons and condensation enter the oil which leads to premature aging of the oil
• At high engine temperatures, these components evaporate in the oil circuit, which further reduces the lubrication quality
