The inner air filter, also known as the safety filter, is the last and most important line of defense for the engine. Its job is to capture the finest dust that could get past a damaged outer filter. While its wear doesn't give immediate symptoms like black smoke or power loss, its failure or absence leads to the silent death of the engine. Even a small amount of silica dust entering the cylinders acts like sandpaper, destroying pistons, rings, and the turbocharger.

The filter is fully adapted to work with the outer filter and the original housing, ensuring the integrity and stability of the entire system.
The REDX brand is a proven and safe alternative that offers filtration quality comparable to original parts at a much better price.
The inner (safety) and outer (primary) filters should always be replaced at the same time to ensure complete engine protection.
After replacing the filters, ensure the filter housing is properly closed and all intake hoses are sealed. A leak after the filter means dirty air is entering the engine.
When inserting the new inner filter, maintain maximum cleanliness and ensure that no contaminants get inside the housing.
Answer: The inner filter is always replaced with the outer filter, typically every 500-1000 operating hours, depending on the manufacturer's recommendations and working conditions.
Question: Can I blow out and reuse the old inner filter?Answer: Absolutely not. The inner filter is disposable. Blowing it with compressed air destroys its structure and filtering ability, which is equivalent to having no engine protection.
Question: Can I operate without the inner filter?Answer: It is extremely dangerous for the engine. Even short-term operation without the safety filter risks dust entering the cylinders and leads to irreversible damage.
