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 provide 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 Intakes are not legal for use in California and other US States adopting California emission standards.

Customer Feedback

Hi Folks,
I am a K&N air filter fan.  I have been using K&N filters for years on my vechicles i.e., 2004 BMW F650GS 652 , 2005 APRILIA Pegaso 650 Strada 660, 2008 HONDA Civic VII Type R 2.0L. It is economicial, green, and powerful for engines.
The question is no K&N air filter for my motorcycle 07 Suzuki AN400s/Burgman K7? That left me disappointed.  I think this model is a hot and popular. Suzuki has already sold this models for over 500,000 vechicles arround the world.  And, this model is manufactured for years. The air filter design is also suitable for K7,K8,K9, K11. I think this evidence would give significant motivation to design an air filter for the Burgman K7+. Why not produce this model's K&N air filter for the benefit of all Burgman riders?
Thanks!

I've have never been disappointed by the quality and value of a K&N filter. I've purchased one for every vehicle I've purchased in the last 25 years. I keep my cars to 200k+, Motorcycles to 80k+, and all sold running well. K&N air filters lowers cost of maintenance, boost performance and efficiency of the vehicle. Acura Legend 290K Toyota Celica 287k, Honda GL1100 91K, Passat TDI 240K, Honda ST1100 89K and Currently Yamaha FJR1300 43K & Toyota Corolla 88K.

No issues out of the box; filter fit right in place within the factory Honda box. I can tell an improvement in power when I step on the gas, which is needed out of a 4 cyl engine. Have used K&N Filters in my V8 truck with the same increased response. Great product, no complaints
