The performance and reliability we receive from using K&N filters is impressive. We have a simple rule at Motoworks the parts we put on our bikes have to be the best, improving power and performance. If it works we use it. That’s why we built a partnership with K&N from the beginning. We look forward to many more championships.

Very good service with my order and delivery time. Installed on my 2013 Can-Am Spyder ST-S, by my dealer on 6/8/14. The 40 mile trip home did not provide much time for evaluation but there is a noticeable improvement in performance. I will be checking on what effect is has on the M.P.G. etc. My previous experience with K&N air filters on Harley's has always been very positive in all respects.

I would like to provide some feed back to you guys, in October I ordered an air filter & received it promptly with no problems. The last week in November I ordered 2 more air filters & using the tracking number was able to determine the package arrived in Australia on the 1st of December. On the 10th of January I still had not received the package and was unable to track it. My local post office was not able to provide any more information either. I went onto your live email service & corresponded with Richard, he was not able to track the package past landing in Australia. Richard took the view the package had become lost, he took my details & told me that he would send me a replacement order. In received this order on the 17th of January with no problems. Thank you very much for the prompt response to my missing order, it is nice to know that there is still people out there that value & offer great customer service. On your air filters, all my vehicles & toys now run K&N filters ( 2 offroad motorbikes, a Can-Am Commander & 2 Landrover SUV's ) These all have benefited from the improved air flow & have all increased in performance. Once again thank you & any future vehicles I get will soon have a K&N air filter fitted to it. Keep up the great work.
