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.

Features:

  • Guaranteed to increase horsepower and improve acceleration
  • Custom designed and engineered for each application
  • Works with OEM computer system
  • Includes the world's best air filter, the K&N filter
  • Easy to install
  • Up to 100,000 miles between servicing
  • Million Mile limited warranty

Your OEM air induction system is a compromise between induction noise considerations, underhood space limitations and engine airflow requirements. Replacing that system is an easy way to improve engine performance. Increasing the airflow and air volume into your engine will result in more horsepower and torque and possibly more miles per gallon.

The heart of the 57i Series Induction Kit is the world famous K&N air filter. The kit includes the largest air filter possible for the application, much larger than the size restricted filter that came in the factory airbox. The K&N air filter's increased surface area provides less restriction and more airflow, while capturing and holding more dirt. Depending upon the application, the filter is either directly attached to the throttle body or indirectly attached with a flexible tube.

K&N uses a dynamometer to design its air intake kits to make the most horsepower possible. But their power figures aren't based on just one vehicle, but rather an average of runs by a number of vehicles. This means repeatable numbers and horsepower claims you can count on.

Every 57i Series Induction Kit comes complete with everything necessary for installation, including comprehensive installation instructions. All adapters are manufactured from high quality materials such as steel, aluminum, silicon or reinforced nylon, to ensure long life. The K&N filter can go up to 100,000 miles before cleaning is required. And the K&N air filter is guaranteed for one million miles.

great oil for your engine; feels very smooth in general
The Best motor oil I have used. I recently began using this brand and 5W-30 instead of 0W-20 in my Chevy Silverado; noted smoother operation and no lifter ticking sounds. There feels like there is better engine protection which should add to long-term durability. This is compatible with trucks as well as cars. Probably adds a few better numbers on gas mileage too.

The Best!!
As a proud owner of a BMW 328i Wagon, I'm always on the lookout for the best products to keep my car running smoothly and efficiently. After doing some research, I decided to give Liqui Moly Special Tec B FE SAE 5W-30 Motor Oil a try, and I'm extremely impressed with the results. This motor oil is specifically formulated with synthesis technology to meet the high-performance demands of modern engines, making it an excellent choice for my BMW. The 5W-30 viscosity rating ensures optimal lubrication and protection, even in extreme driving conditions and temperature fluctuations. I've noticed a significant improvement in engine performance since switching to this motor oil—the engine runs quieter, smoother, and more efficiently, with better fuel economy and reduced emissions. Plus, I appreciate the long-lasting protection it provides, helping to extend the life of my engine and reduce the need for frequent oil changes. The 5-liter size is convenient and cost-effective, providing plenty of oil for multiple oil changes. Overall, I highly recommend Liqui Moly Special Tec B FE SAE 5W-30 Motor Oil to BMW owners looking for a premium motor oil that delivers exceptional performance and protection.
