The K&N AirCharger 63-3077 air intake system replaces 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 factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 63-3077 air intake comes with a K&N high-flow air filter and a covered heat shield that mounts onto the inner fender near incoming outside air. This allows cooler, denser air to be directed through a custom molded intake tube into the engine’s throttle body for a guaranteed power gain. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install requiring only a couple screwdrivers, a socket set and wrench. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

K&N 63-3077 Air Intake Product Reviews

Installed the filter and it was fairly easy. Haven't seen any improvement in performance to date, but will be towing my 39 footer soon and I hope it helps.

Easy install. Roughly 45 minutes with simple tools. Day after install reset my fuel economy and took my 2013 GMC 2500 HD Duramax for a 3 hour trip noticeably throttle response (don't have a dyno so can't claim horsepower) AND gained 2.5 MPG. That's right. 2.5 more miles to the gallon. The truck only has 45,000 miles on it. Fuel savings will pay itself off in no time. Great product, definitely would recommend it to anyone.

This was a fun project to do with my son-in-law. The directions were clear, making the installation a breeze. Our test drive showed a tach of only 800-1200 as we went through the gears.

Installing the intake and filter was very easy. The instructions walked you right through it. I like keeping the air filter clean and now it's so easy to keep it that way.

Everything was as promised the only problem was the two bands at the air-mass sensor could be wider. I had one slip off and trip a fault code, it's just hard to get them centered and tight there isn't alot of wiggle room. I do think my mileage has went up a little. Power wise I don't know about but I pull an RV so any help will show on grades. Hey where's my hat??

I love my new k&N performance intake kit. I did notice an increase in horsepower haven't noticed a difference in fuel mileage yet but it only took about an hour to install. Great product. I will continue to buy K&N products
