K&N Gen I Air Intake System 57-0421 with Rotomold Tube For Vw Golf 2000

K&N 57i Series induction kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provides even more airflow at lower restriction than a K&N O/E replacement filter which is limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Series Intakes are not legal for use in California and other US States adopting California emission standards.

Top 7 Reasons to Upgrade to a K&N Air Filter

Enhanced Performance: K&N air filters are designed to improve airflow, allowing your engine to breathe easier and generate more power. This can lead to noticeable gains in horsepower and acceleration.
Cost Savings Over Time: Unlike disposable filters, K&N air filters are washable and reusable. This means you only need to buy one filter for the lifetime of your vehicle, saving you money in the long run.
Superior Filtration: K&N filters provide excellent filtration, protecting your engine from harmful particles and debris. This helps maintain engine health and performance.
Easy Maintenance: Cleaning and re-oiling a K&N filter is straightforward and can be done at home. This convenience adds to the overall value and longevity of the filter.
Eco-Friendly: By using a reusable filter, you reduce waste and contribute to a more sustainable environment. This is a small but impactful way to lessen your environmental footprint.
Material: K&N's reusable High-Flow Air Filter enhances performance by combining pleated, breathable cotton with their signature red filter oil. Unlike paper filters that clog quickly, K&N's oiled cotton filter absorbs dirt and dust, allowing up to 50% more airflow. This ensures a continuous flow of clean air into your engine. Additionally, while disposable filters need replacement every 12-15,000 miles, K&N filters can last up to 100,000 miles before requiring cleaning under normal driving conditions.
