The K&N 77-2576KTK Air Intake fits some Ford Flex, and Ford Taurus models. See vehicle applications link for details.
The K&N 77-2576KTK high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Ford Flex and Taurus models. The restrictive factory air filter and air intake housing on your vehicle are replaced by this K&N air intake system which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. The improved air flow allows your engine to inhale a larger amount of air than it would from the stock air intake. The intake tube has an attractive textured black powder-coat finish that's made to last and it accommodates the factory mass air sensor, crank case vent hose and a replacement silicone EVAP hose. The oversized cone shaped 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 usually in 90 minutes or less using existing factory mounting points. The tools needed are a screwdriver, pliers, ratchet set and an Allen wrench. Some K&N 77 series air intakes are not legal for sale or use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the K&N catalog or website for vehicle applications and specific CARB status for each vehicle and air intake.

Easy to install and love the new sound.

Pretty easy to install. Installation instructions not the best. This is the 2nd one I've installed so that helped. Still waiting to see if it ups gas mileage but you can feel the power boost and hear the growl when you step on it. If you want to hear how your engine is working, then this will do the trick.

I bought this cold air kit to install on a 2014 Ford Taurus, and to my surprise, I was some what impressed. I wanted to increase the throttle response and acceleration on this modern day lead sled. Well, I got a lot of noise under the hood that sounds pretty good, but to my dismay I still have throttle lag. I even installed the (Brand Name) pedal max and still have throttle lag, I should of bought a Stang GT instead.

Great kit. Very easy to install, even without much wrenching experience. If you've assembled [Brand Name] furniture you can do this no problem. Best of all you can do most of it in 20 minutes at your kitchen table, and then only ten minutes in the garage or driveway (or supermarket parking lot). The kit itself is very well made and attractive, and the component parts all seem to be of good quality. But the proof of the pudding is in the eating, and when you have this all hooked up and go for your first WOT run you will guaranteed have a smile on your face. The sound it provides is spectacular. It's a real low throaty roar on acceleration, but the car stays quiet under normal revving, so it's still quiet on the highway. I combined my kit with an [Brand Name] tuner and custom tune from [Brand Name], and I recommend combining the two. Last thing, bear in mind the standard Flex comes with a cold air intake. This one will give you some additional responsiveness and great sound, but apparently is not recommended if you live in desert heat areas, as the metal body is less heat efficient than the plastic stocker under high temperatures, leading to an increase in the IAT--the opposite of what is desired. But if you're in more temperate climes you'll love it.

It''s pricey but so worth it !!! The sound is deep and growls with the 3.5 v6 model , I love it , not to many reviews on this so that's why I had to give it one ! There is a power gain !

Great Product. Easy to install, looks good and the improved power and responsiveness is nice. The sound the car now makes is awesome. Sounds like there is a performance exhaust. Has a nice growl under hard acceleration.
