Good instructions led to easy installation. Stickers provided alerted the dealership not to touch the air filter during routine maintenance.

Great deal. I couldn't believe I ordered this from California and it arrived at my door in Toronto the next day. Fantastic service.

I have used K&N air filters for several years now. As far as I am concerned, they are the best on the market. My 2017 RAV4 gets better gas milage and does seem to have more horse power. I don't need to replace them just clean them which is actually pretty easy.

Product was easy to order and delivered quickly. It fits the air filter box perfectly on the car.

So far so good... K&N filters sell themselves, and if you haven't switched to them yet, do so and you will never go back. Seems expensive, but if you keep a vehicle for any length of time, they are cheaper.

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.

Wanted a cold air intake, but this will have to do.
