The K&N 77-2573KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Ford Explorer 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. More air means more usable power and acceleration throughout your engine’s RPM range. The 77-2573KP 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. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive chrome-like finish that's made to last and it accommodates the factory mass air sensor and a replacement silicone crank case vent hose and brake booster vent 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, 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.

Customer Feedback

Installed the cold air intake in my 2014 Ford Explorer Sport. Even with the turbo, the response is improved and the sound is awesome!

My wife was complaining about a musty smell for the last three years every time she turned on the air conditioner. I checked my owners manual for the 2011 Ford Explorer and no cabin filter was listed for that year. My Explorer was one of the first ordered and shipped to St. Louis. After talking to some of my friends at Ford, I came to find out that since my car was one of the first produced, they discovered that they failed to list the cabin filter in the manual, that being fixed on all later models. Once I discovered the error, I went to K&N to look up the replacement. She's hasn't had much chance to use the air conditioner yet but the fact she's no longer complaining convinces me that your product is working. I've been using K&N air filters for the past 15 to 20 years, love the product, and I'm sure the cabin filter will perform as well. David
