K&N 33-2477 Air Filter Product Reviews

Wednesday, December 13, 2017 - Part 33-2477
I have purchased many K&N products and when my 2013 Honda CR-V needed a new air filter I went with the best - K&N. The ordering and delivery was fast and easy as was the installation. What surprised me was the engine is quieter and my fuel mileage is better (about 1 mpg over the first 2 tanks of fuel). Great product, thank you.

This is the third vehicle we've replaced the factory air filter with the K&N filter. We notice more power and better gas mileage. You just clean it as directed, which is quite simple, and you're back in business. I feel it's a wise investment for my cars.

I changed the air and cabin filter on my wife's CRV. Shortly after we took a road trip to Quebec (roughly 400 miles one way). The CRV's mileage exceeded 30 mph for the trip. An improvement of 3-4 mpg before changing the air filter to K&N. The improvement is similar to my previous experience with other K&N filters.

Just what the doctor ordered. A 1 million mile durability rating pays for itself in the long run. Thanks for everything K&N.
