Bosch Air Filter Insert (1457433961)

The task of the air filter

• 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

Change the air filter regularly according to the vehicle manufacturer's specification.

The 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
