The big "deep breathing" engine in your truck or SUV needs a 77 Series High-Flow Performance Air Intake Kit to unleash all of its power. The kit starts with an oversized conical high-flow K&N air filter, installed in place of the restrictive factory airbox. The large increase in filter area over the stock airbox filter results in a huge increase in airflow and a greater capacity to capture and hold dirt.

The increased airflow continues with a free-flowing mandrel-bent aluminum intake tube in place of the factory air path. The intake tube is available in several finishes. Most kits also include a heat shield that seals against the hood and isolates the filter from engine heat. The reduction in air intake temperature results in a cooler, denser air intake charge and even more horsepower. All components are mounted and connected with high quality materials such as steel, aluminum, silicon or reinforced nylon, to ensure long life.

K&N uses a dynamometer to design its air intake kits to make the most horsepower possible. But their power figures aren't based on just one vehicle, but rather an average of runs by a number of vehicles. This means repeatable numbers and horsepower claims you can count on.

Every 77 Series High-Flow Performance Air Intake Kit comes complete with everything necessary for installation, including comprehensive installation instructions. The K&N filter can go up to 100,000 miles before cleaning is required. And the K&N air filter is guaranteed for one million miles.

2005 Jeep Grand Cherokee | Posted by | (Lynnwood, WA)

The unit arrived in perfect condition- good packaging. Instructions were easy to follow and concise, I didn't even have to go to YouTube to see it done! This thing fits nicely and looks fantastic. I've show it to several friends who were all very impressed. I think I may have sold a couple of units! Performance increase is undeniable- especially off the line and when passing. It gave my jeep a throaty howl when I open up the throttle body, but it's still quiet under grandma driving conditions (like when there's a cop next to you). I haven't had it long enough to tell about mileage. I'm having so much fun listening to it open up, mileage has probably gone down, but once I get over myself and drive without my foot on the floor I'm sure that too will improve! All the other claims made by K&N are absolutely true! I recommend this product highly! There is no other type of product that will make this much difference for just a few hundies. Talk about bang for the buck!
