My Honda Civic Hybrid is the third vehicle I have added a K&N filter. My Dodge Caravan picked up 2 MPG and more power, but my hybrid picked up 7 mpg which I thought was fantastic.

To all Honda Civic 2014 LX sedan owners,with CVT automatic transmissions who say my car doesnt have enough power.Get a KN filter and feel the power you thought was missing.Try it, you will be pleased.

I drive a 2005 Honda Civic EX Coupe. I drive about 90km per day and have put about 45,000km on in the past year, the majority of which is highway driving. Naturally, any increase in fuel economy is music to my ears. The car is rated at 5.9l/100km (40MPG), and cruising at 100-105km/h resulted in obtaining around 6.2l/100km. I installed this air intake kit about 30,000km ago and since that time, I have been seeing figures around the 5.5l/100km, under the same driving conditions. One particular trip, I saw 4.5l/100km. This air intake has paid for itself already, and will only continue to save money. I bought this air intake kit for the sole reason of better airflow and achieving better fuel economy. Power increase isn't overly apparent, but the increase in fuel economy has exceeded my expectations. I would highly recommend this to anyone who uses their car as a daily commuter and puts on a lot of kilometers as it will pay for itself quickly. Thanks K&N for engineering some amazing products! This was my first experience with your air intake kits and I am blown away. You rock!
