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.296.99

The kit was easy to assemble, but the most of the hose clamps were one size too small. I had to reuse the existing one from the factory intake.1 people found this review helpful.Was this review helpful for you?

I had this installed on my 2008 GMC Sierra 1500 4x4. After 2,000 RPM when you hit the gas pedal you know it's working. No hesitation, definite increase in horsepower and torque. Also installed a Poweraid Throttle Body Spacer right after and noticed another increased difference.6 people found this review helpful.Was this review helpful for you? YesNoShare this review:
