Internal combustion engines consume vast quantities of air. Depending on different conditions, air can be dirty and create oily deposit, which is very dangerous for the engine. Air filters function is to protect the engine from external contamination.

When an air filter starts to block, the air flow through it becomes restricted, causing the air/fuel ratio to change, causing deterioration of engine performance and high fuel consumption.

Some commercial and off-highway applications incorporate a “safety” filter which fits inside the main air filter element, and protects the engine should the main element rupture.

Sogefi Pro air filters fit the manufacturers needs.
