On the Safe Side with Bosch Air Filters Beware of Inferior Filters!

High-Quality Air Filter Filter Medium

Low-Quality Air Filter Filter Medium

Possible Expensive Consequences

u Increased wear of the engine u Accumulation of dirt on the air-mass meter

High particle-separation rate by microporous filter medium

Low-quality filter medium

Large dust-holding capacity through high number of pleats

Small number of pleats

u Reduced service life

u Poor fuel-mixture preparation u Reduced engine performance u Increased fuel consumption

Moisture resistance through impregnation with special resin

Conglomeration of pleats due to wetness

Fire hazard caused by aspirated cigarette stubs or backfire

Inflammation protection through special coating (according to the OE equipment)

u Vehicle fire

Low-Quality Air Filter Stability

High-Quality Air Filter Stability

Possible Expensive Consequences

u Reduced service life u Poor fuel-mixture preparation u Reduced engine performance u Increased fuel consumption

Permanently stable pleat geometry through sufficiently dimensioned glue beads

Unstable pleat geometry

Low-Quality Air Filter Seal

High-Quality Air Filter Seal

Possible Expensive Consequences

u Increased wear of the engine u Accumulation of dirt on the air-mass meter

No bypass of unfiltered air due to high-quality polyurethane seal

Poor processing, low-quality sealing material

u Reduced service life u Poor fuel-mixture preparation u Reduced engine performance u Increased fuel consumption

No loss of filter surface through careful processing of the sealing material

Excessive use of sealing material
