Let me paint you a picture: there I was, standing in front of my car, wondering how to make it feel like it just stepped out of a luxury spa. And then it hit me – the K&N Engine Air Filter. Let me tell you, this filter is like the VIP pass for your car's lungs, and if cars could talk, mine would be singing its praises!First things first, the reusability factor is like hitting the jackpot. Forget the days of replacing your engine air filter every few months – K&N says, "Why do that when you can have a filter that lasts longer than the lifespan of a fruit fly?"

Just a quick wash, let it dry, and voilà – your car is breathing in that fresh, clean air like it just won the air quality lottery.Compatibility? K&N has got it covered. My car happens to be a Ford Edge, and let me tell you, the K&N Engine Air Filter fits like a glove.

Compatibility with various Ford and Lincoln models means you can share the K&N love with a fleet of vehicles.Installing this bad boy was smoother than a cat burglar in the night – stealthy and quick. The instructions were so straightforward that even my neighbor's parrot could have followed them. It's like K&N knew that not everyone is a car guru, so they made it idiot-proof (thank you, K&N, for saving me from looking clueless in the garage).Let's talk performance. My car is now a beast on the road. It roars when I hit the gas, and I half expect it to sprout wings and take flight. The acceleration is smoother than a jazz saxophone solo, and the engine purrs like a contented kitten. I'm pretty sure my car is plotting to challenge a sports car to a race – and with the K&N filter, it might just win!In conclusion, if you love your car and want it to feel like it's cruising on a cloud of awesomeness, the K&N Engine Air Filter is the only way to go.

High-quality low restriction air filter.
Is CNN filter will increase your horsepower slightly because it allows air to flow more easily. More air means more fuel which equals more power. I like the fact that it can be cleaned and reused over and over and over again. You will spend money on the cleaning Kit to clean these filters, but overall over the life of your vehicle, you’re going to save money by having this reusable filter.

Best lifetime filters you can buy
I use these filters in every car for my air filter and my cabin air filter and I also use them in my house for the filters on my air conditioning. You buy one time and they last for life. Just wash them put them back in and you’re good to go again. You never have to buy paper filters in your house again and it keeps your air much cleaner in your car and your house.

Perfect Fit, Perfect Solution
It’s a solution that uses the factory air box while adding the benefits of a K&N filter. Those benefits include less-restricted airflow, a long-lasting filter that needs to be cleaned every 50K miles, and a suggestion of a little bit more horsepower and MPG. While the latter two are up for debate, the first two are for certain.Worth the investment, highly recommend.

K&N Filter
First off you shouldn't expect miracles from this filter. They work really well if you keep you're expectations realistic. I've used these on my last 8 vehicles and everyone has performed better and increased gas mileage at least 2 MPG. Generally you can run them a long time between cleanings if your not using them in dusty areas. Every vehicle I've put them in runs freer, you can feel the difference immediately. An engine is an air pump and the more air it can push through it the more power it will generate and the less fuel you will use. K&N claims approximately 15 - 20 HP gain and I can say that it is very believable. I just put this in my new MKZ AWD and I went from 25 MPG to 27 MPG immediately. Now that summer temperatures are here it has gone up to 29 MPG. I will continue to buy K&N filters for as long as I keep buying cars. They really are that good. The more you drive your car the better these look. Your not throwing out a filter every 10,000 miles and your picking up the savings on your increased gas mileage every mile you go. The filters easily pay for themselves in the first few months of ownership. I have a hard time believing some of these reviewers on here that claim no gains at all. As a Certified Calibration Technician I keep very detailed records of my gas mileage before and after I install each filter on my new vehicles and everyone has showed a minimum of 2 MPG rise in like driving conditions. And lets remember that even if you saw no gain in fuel economy you would still save a lot of money on the cost of just buying replacement air filters over the life of you're car. These will last as long as you own you're vehicle.

Fits 2025 Ford Explorer 3.0L
Installed in my 2025 Ford Explorer ST in less than 5 minutes. Exact fit with no modifications whatsoever.Warning: the clips non the airbox are a little tricky to reattach You need to press the clip in the middle, instead of the top like most would think.Recommended

Always an excellent product
This is the fifth set for my different cars and trucks over the years and these have never disappointed.I do notice a slight improvement in MPG. I don’t notice any change to performance. But I didn’t buy them for performance gains. I like that I can clean and reuse. I usually clean them out seasonally. Same time as when I replace the filters for the HVAC.
