Bosch Air Filter Insert (F026400334)

You should change your air filter regularly and according to your vehicle manufacturer's specification. The air filter plays an important role in the daily running of your vehicle. 

In most instances, the task of the air filter is:

• To protect the engine against dirt particles in the intake of air
• To protect the engine against wear
• To safeguard the air supply in the mixture generation
• To reduce the noise level

After some use, the air filter does get dirty with various particulates. Not changing the filter often, and leaving the filter dirty could have various consequences on your engine's performance. 

Consequences of a dirty filter:

• Poor air-fuel mixture generation resulting in reduced engine power and increased pollutant emissions
• Increased fuel consumption
• Increased engine wear from particles
• Problems starting your vehicle

The prerequisite for flawless operation: A tight fit

Leakages and porosity lead to a bypass of unfiltered, unmetered air into the intake duct. Consequently, Bosch air filters are made with a longer-lasting seal made of polyurethane:

• Exact fit matched to the housing shapes
• Unevenness in the housing is compensated for
• Flexibility and suppleness in the seal across the entire service life of the filter
