The K&N 77-2570KTK high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system. 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. More air means more usable power and acceleration throughout your engine’s RPM range. The 77-2570KTK air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space and connects up to the factory fresh air scoop. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive textured black powder-coat finish that's made to last and it accommodates the factory mass air sensor and air temperature sensor. 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 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.

 I installed this intake on my 2011 E350 Super Duty van 1 week before a 10,000 mile road trip around the US. Cant say enough good things about this system. Great power right out of the box. Sounds amazing and helped with fuel mileage. Was a must have for the mountains out West.

 Quality product and straight forward installation. Looks really cool when you open the hood, too!
I can feel the performance increase but haven't really had a chance to check fuel economy. I have at least one friend who is getting one for his van since he checked out mine.
Excellent product.
