The K&N 77-2575KS Air Intake fits some Ford Explorer models. See vehicle applications link for details.
The K&N 77-2575KS 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 77-2575KS 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 silver 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 vent line. The tools needed for installation are a screwdriver, pliers, ratchet set and several wrenches. 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.

K&N 77-2575KS Air Intake Product Reviews

Saturday, February 11, 2017 - Part 77-2575KS
I installed this air intake on my 2014 explorer about 2 months ago, after it spewed a couple codes that indicated my fuel mixture was to rich. The installation didn't take much more than an hour and the instructions were thorough and straight forward. The performance, real or imagined, is incredible. The SUV seems to have much more power and the sound makes it seem even more powerful. I hit the gas pretty hard to test the acceleration and it hasn't thrown any OBD codes anymore. I will definitely purchase K&N air intakes for any future new cars that I buy. Great product

This is an awesome product. I have a 2014 Ford Explorer XLT 4wd and for those who want more power in the Explorer, this is the part. You can feel the difference, plus the sound. I love the sound....

Put the K&N Intake on my 2013 explorer and it sounds amazing. I smile every time I push on the gas pedal, had to do something to it after getting rid of my fun, daily driver. LOL!

Super easy install and was everything promised. Having a hard time not trying to crush the gas pedal to hear my vehicle roar at the higher RPM's. Feels like it has a little more pep in its step but unsure about MPG at this time due to my afore mentioned problem with the gas pedal. If it ends up doing nothing more than just looking good when I lift my hood ill be fine with that as well. Hope this helps with making someone else's wallet lighter.

Great product. Installation was very easy as I found an online video. The sound produced is nice and I noticed an increase in horsepower and a slight increase in gas mileage per gallon. I was surprised by the air restriction of the OEM air system. The K&N product is very well made and I would recommend this product.

Enjoying my air ram intake a lot! Sounds great when I past some punk on the highway. Very easy to install. It only took 45 mins. but I was taking my time. There was a wielding slag on the inside of the tube. Just cleaned it up. Also an added bonus when from 17.3 to 18 mpg.

I have designed my own intake kits during my younger years. This by far is the best kit for the money. 30 minutes to install and the pick up is very noticeable. I didn't realize how awful the factory intake was prohibiting my air intake until I installed this K&N kit. It even sounds great. Nice job!
