77 Series High-Flow Performance Air Intake Kit by K&N®. This intake kit is designed for the larger engines typically found in trucks and SUVs. It replaces the factory air intake system with a free flowing K&N air filter and custom designed air intake tube. Extensive dyno testing improved intake airflow and allows these big engines to develop even more torque and horsepower. The end result is better acceleration you can feel.

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.

Good looking upgrade, that's easy to install and about 3000 rpm give the engine a nice throaty sound.

This is an amazing product. The installation was pretty easy. I only had one speed bump with installation. They send you two extension hoses that are the same size. This made it nearly impossible to get the extension (which fits perfectly over the small hose) over the larger hose. I ended up using a little vaseline and that baby slipped right on. After you get it installed I'm sure you will be satisfied with the look and the gains in hp.

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!

Purchased based on product description. Glad i did once i installed the K&N air intake as the bottom on the wheel well had a direct open space to the ground, so "if" it does what is says it does will serve a great purpose. Just will not know until I have to deal with a rain storm and see how it works. Did take a little effort to get into place correctly.

Worth the money because it adds an extra layer of protection just in case anything happens. Wouldn't hesitate to purchase this in addition with a KN CAI.

This performance intake was the game changer in my Rangers system, it sucks so much more air now I'd never ever go back to the stock, the throttle response gain is more then worth the money.
