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.308.47

The product works good. Installed easy, with good instructions. Disappointed with K&N sending out a product with plastic screw in breather pipes adapters. I replaced them with brass fittings from the local Auto shop. Also, the thread where the fittings go, had excess chrome. Paul, Australia.Was this review helpful for you?

It was very easy to install, nice sound under the hood. But still not seen difference with the gas, I think I'm using more gas with the air intake than without this well. I've to be checking all the time with this but looks like gas is going away faster than before... the performance is awesome.Was this review helpful for you?

The instructions were too the tee, everything matched and everything fit perfect. No problems at all, so if u have a 2011-2013 Ford Edge, this product will fit perfect, and it only took me and my dad about 45 mins to install all hoses and mass air flow and nipples. Everything fit perfect and the car gas mileage went up 4.6 more miles a gallon and sound like a beast when I get on it. So, if you're looking for a cold air intake, this is the one you need. It's the K&N filter 77 series.Was this review helpful for you? YesNo(5)APPEARANCEEASE OF INSTALLATIONPRICE/VALUEQUALITYK&N Intake| Posted by Mike E. | 2007 Ford Edge (Kelowna, BC)
The intake was very easy to install. All you got to do is follow the instructions that they give you. The heat shield was kinda of a pain to get in but it makes a big difference once its in, and whether or not it's sucking in hot or fresh air from the fender. I also bought a steeda intake throttle spacer which pushed it into the headlight a bit but it still fits. I was just thinking about cutting the intake pipe to make the filter not rest on the headlight housing. The steeda intake throttle spacer spacer is about an inch thick and if it wasn't installed the intake would fit perfectly.Was this review helpful for you?

My friends and I use K&N on all our vehicles and I don't think any of us have anything bad to say about them. A couple tools, 1/2 hour of time the old one is out, new one is in. Ordered this from another website. Waited on them for 3 weeks without hearing anything from them. Called them and they said it was on back order and probably would be another month. Canceled that order, ordered it on CARiD and it was at my house less than a week later.Was this review helpful for you?

This was a great product. Increase my horsepower and acceleration. It also increased my mpg. I woul get 18 city and 24 highway and now I get 22 city and 35 highway. The sound coming from the intake will definitely turn heads!Was this review helpful for you?

I purchased this product not really knowing what to expect on my 2011 Taurus. I must say that I am absolutely pleased with this product and the ease in which it went on. The way it sounds, and the increase in MPG; which by the way went up by 3 to 4 MPG on the highway, I can not tell a lie, I have yet to determine what I actually get in the city because I can't keep my foot off the throttle... It just sounds that darn good! Putting this product on did not cause my check engine light to come on which made me happy. In summary, know that I am the type of person that worries about check engine lights coming on, spending money for something that may not work like they claimed it does. But this here was worth every bit of money I spent on it.Was this review helpful for you?

The Intake system you sold me works great. It has given my truck more pep and when I push on the footfeed, I not only can feel more power, but I can here it as well. Now I need some tuned header's and some dual exhaust and I'll be set. But right now, I would like to have some Chrome bed rails. DannyTVickWas this review helpful for you?
