  • Designed to Increase Power
  • Million Mile Limited Warranty

The filter arrived prior to the estimated time, very cool. The 2014 Accord has a filter box that's easy access and the K&N dropped right in place. I like the alert sticker that came with it and put it on the filter canister. This will save me a lot of money over the course of ownership. It will be difficult for me to say if it makes a big difference over the stock filter. My car has just 600 miles. But I can certainly hear the increased air flow under heavy acceleration. All is well & Good!

I can feel the difference. Inexpensive way to gain a little power!

I have always had a K&N filter or intake system in every vehicle I own. So when when my wife got a new Honda Accord I ordered one right away. No surprise, great product! The fact I got a free hat was just a bonus!
