K&N 33-5031 Air Filter Product Reviews

I just want to let you know that your filters are great. Had a 2010 Honda CR-V that someone decided to rear end me six weeks ago and I had your filter in it. Before the insurance company towed it away for scrap I took out the cabin air filter. It fits the 2015 Honda CR-V that I bought. Had to buy the 33-5031 for my new one.

Noticeable change in performance after I installed the K&N filter in my 2015 Honda CRV although I haven't had an opportunity to check mileage. I suspect it will also be better [as it has in the past with other vehicles] Keep up the good work.

Great replacement air filter. Every vehicle I have owned, I have dropped one of these in it and have never been let down. Best product out there. Keep up the great work.

Noticed an immediate difference after replacement - more responsive vehicle performance and better fuel efficiency. After driving on first full tank of gas (60L) after installation, got 85 km over my previous avg. distances on a full tank. Getting 17 increase in fuel efficiency, means less time at the pump and more money in my pocket. Overall, great product and super easy to install. Tip: Keep your old air filter to place it in the vehicle while you clean/wash and let the K&N filter air-dry for 24-hrs before re-oiling for re-use. This will allow you to continue to drive your vehicle and keep the K&N maintained every 80,000 km (50,000 miles) - learned this trick with my previous vehicle that was outfitted with a K&N as well. Also, the re-oiling kit is reasonably priced and very easy to use, plus expect it to last up to 3-4 cleanings.

I have immediately noticed an increase in my gas mileage. At least 10 if not more. I drive a 2015 CRV the K&N air filter is just the ticket.
