Built for performance and show utilizing the highest quality components, the K&N 77 Series High-Flow Performance Air Intake is a free-flowing mandrel-bent aluminum tube induction system designed for Trucks and Sport Utility Vehicles. 77-Series air intakes come with K&N's Million Mile Limited Warranty. K&N intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger amount of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable and reusable. Most of our intake kits are relatively easy to install using tools commonly available (see installation instructions). Some 77 Series Air Intakes are not legal for use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the K&N catalog or website vehicle parts search for specific CARB status.

Ridgeline Testimonial
    Hey, my brother and I just installed your intake for my Honda Ridgeline... I was expecting it to sound cooler and have more horsepower... but the difference we got was literally amazing.

    First off, the intake sound that thing makes is insane!  It took my quiet, mundane little V-6 sound and made transformed it into a deep, loud rumble.  I didn't think my truck /could/ rumble, but now it does.

    Second, the horsepower gain is more than just 'noticeable'.  Getting on the highway and passing the difference in remarkable.  The first few times it caught me by surprise and gave me a decent scare, but now I've just learned to enjoy it.

    Best of all, your instructions were so clear and easy that even inexperienced guys like my brother and I were able to install it in less than an hour.  Keep up the good work!

So far, so good. My son & I own a 2008 Honda Ridgeline RTS. If I resist stomping on the gas pedal, do strictly highway driving, drive the speed limit, and dependent on how strong the ethanol is in the gas, I can average 20 miles to the gallon. My son & husband installed this air filter into both of our vehicles. My son does mostly city type of driving, and I do a mixture of driving. So far I have gained a bit of an increase in the mpg driven over what I had during these winter months. I have definitely gained an increase in the amount of miles driven per tank.
