Horsepower you can feel!
As with all our kits, when you bolt-on a 57i intake, you will notice the difference the next time you drive your car. Our 57i Intake Kits are a great way and in many cases the only way to maximize airflow and engine performance.

They will replace the factory air box providing both High-Flow air filter technology and a larger air filter size. This winning combination will increase horsepower and sound great too.

Break out of the factory air-box
57i Series Intake 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 bonnet. Each kit is designed to provide power throughout the RPM range. Gen 1's take advantage of the added airflow provided by an oversized air filter released from the restrictive factory air box.

Tech Talk
These kits bring engine airflow out of the factory box by providing a large size open-air conical or round High-Flow Air Filter. The extra surface area of these open-air air filters provide even more airflow at lower restriction than a K&N O/E replacement filter which is always 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 then either directly attached to the engine carburettor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adaptors are made from high quality materials such as steel, aluminium, silicon or reinforced nylon and ensure long life.
