FILTRON AP 133/5 is a high-quality air filter designed for effective purification of the air drawn in by a combustion engine. Manufactured by the renowned brand FILTRON – one of the leaders in the automotive filtration industry – it guarantees precise fit and performance comparable to original OE parts.

Application and function of the air filter
The air filter is a key component of the intake system. Its main functions are:

• Cleaning the intake air of dust, sand, soot, and other small contaminants.

• Ensuring optimal combustion conditions in the engine, which leads to:

  • protection against premature mechanical wear,

  • maintaining full engine power,

  • reducing exhaust emissions,

  • improving fuel efficiency.

The filter element is made of special cellulose-synthetic materials that provide high airflow while effectively trapping contaminants.

Features and benefits of using FILTRON AP 133/5

• Precise fit – designed according to vehicle manufacturers’ specifications for tight sealing and easy installation.

• High filtration efficiency – removes up to 99% of particles as small as a few microns.

• Optimized airflow – ensures proper air supply for combustion, supporting engine performance and proper fuel-air mixture burning.

• Resistance to moisture and temperature changes – ensures stable operation in various weather conditions.

• Intake noise reduction – improves acoustic comfort inside the vehicle.

Signs of air filter wear:

• Loss of engine power and responsiveness

• Increased fuel consumption

• Irregular engine operation, starting difficulties

• Higher exhaust emissions

• Unusual noises from the intake system

Replacement recommendations:
Standard replacement interval is every 15,000–20,000 km or once a year.
In tough conditions (dirt roads, dusty environments) – more frequently.
The replacement should follow vehicle manufacturer recommendations.
For safety and full intake system performance, replacement should be carried out by a specialized service.
