The K&N 57 Series is designed for many different car models and provides significantly improved airflow to the engine compared to a K&N panel filter alone. Only non-metallic molded polyethylene tubing systems are used here, which reduce air temperature and intake noise compared to a metal pipe. Often, the air path to the engine through the factory-installed air filter box is the "weak" point in terms of maximum engine power. K&N's 57-series air intake systems virtually eliminate all restrictions by replacing the air filter and the entire intake duct on the engine. The aerodynamic intake duct drives massive amounts of air into the engine, which translates into POWER.
The K&N 57 Series is truly state-of-the-art. It uses the largest conical high-flow air filter that can fit into the car's engine bay, and the factory's original holes and mounting points are utilized. The extra filter size provides even more airflow with lower air resistance than a standard K&N panel filter, which is limited to the size of the factory-installed air filter box. The oversized air filter captures significantly more dust and dirt, thereby extending the time before filter cleaning is necessary (up to 160,000 km). When possible, the filter is isolated from high engine temperatures by a heat shield, whose purpose is to lower the temperature of the air entering the engine, which increases horsepower. The filter is then mounted on a specially molded polyethylene tubing system. This process allows the tube to be precisely shaped to reduce turbulence and accelerate airflow into the engine. This is why some K&N tubes have unique shapes specifically designed for each individual car model. Finally, the tube is connected to the engine with adapters made from high-strength materials such as silicone and reinforced nylon, ensuring a long lifespan. Put all of this together, and you have the best high-flow intake system available today.
