This is my second K & N, first one was for the motorcycle. Hoping for an increase in performance and mileage as others report. Its hard to tell on the Camry Hybrid in the winter.

Have used these filters on all of the vehicles I've ever owned and LOVE them. They work great, are easy to clean and save $ over using disposable filters, plus create less waste if you're environmentally friendly like I am. Will never use any other filter.
