We recently purchased a 1999 Honda CR-v with 27,000 miles. It quickly became obvious the little SUV (2.0 liter 120 bhp) would have trouble keeping up with traffic unless the throttle pedal were on the floor.....something I'd rather avoid.

I recalled a friend telling me he had installed a K & N air filter on his motorhome as the filter was extremely difficult and time consuming to get to. He said the motorhome had better performance after the installation. I thought what the heck, what do I have to lose other than $38. Spending the winter in Las Vegas, you can spend that in a casino in a blink of an eye. And if it performs in my CR-v, I'll stick one in my motorhome.

I cannot believe the difference in the CR-v!! On grades where the transmission would have to shift down, the engine now pulls the grade with nominal throttle pressure. No need to shift down. I now have NO PROBLEM keeping up with traffic with the same throttle pressure as before. It's throttle response may not be on a par with the 2002 CR-v we test drove before buying the '99, but it's darn close. (The 2002's have a larger engine and about 30 bhp more). I have not noticed any increase in fuel mileage in the two weeks the filter has been on. Maybe it will come later. Bottom line?.........I'M HAPPY!

Oh......it takes all of 60 seconds to change the filter on a CR-v. Quit thinking about a K&N and get one!

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!

Hey guys I just installed my K&N on my 2013 Honda Civic Si. It's just so freaking crazy the sound and the kick with the Vtec. It's just like a brand new car. The instructions were very easy to understand and easy to install. Go get a K&N now!! Thank you K&N for your amazing product.
