Best Air Filter on the Planet!
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?" Clean it every 75,000 miles? It's like giving your car a spa vacation every few years. My car is probably planning a tropical getaway as we speak, all thanks to the K&N filter. Now, the washable feature is a game-changer. Picture this: your car's engine air filter taking a bubble bath – okay, maybe not literally, but close enough. It's so easy, even your grandma's cat could do it (if it had opposable thumbs). 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. It's like the filter was tailor-made for my car, whispering sweet nothings to the engine as it ensures optimal performance. 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. Reusable, washable, and compatible with a range of Ford and Lincoln models – it's the royal treatment your car deserves. So go ahead, give your vehicle the VIP pass to clean air and top-notch performance. Your car will thank you, and you might just catch it winking at you in the rearview mirror!

Follow the K & N cleaning instructions and purchase the K & N "Recharger" kit.
Great product, noticed the improved performance in my Ford Explorer 2.3L turbocharged engine immediately even before I did a mod to my exhaust system with Magnaflow resonators which further enhanced my engines performance. People often don't realize that over time their exhaust system will start to fail and become clogged, especially if you've had a flex pipe failure which I did. When I had the flex pipe replaced its failure caused the last catalytic converter to become clogged. This last catalytic converter when clogged will drastically impact your vehicles performance and will NOT throw a check engine light as the last catalytic converter is not monitored by my Explorers engine system so I had my last catalytic converter removed when the flex pipe was replaced. No regrets now that I'm getting more air into my engine from my new K & N filter.

Most efficient
Never replace the engine air filter again just wash out and dry and back usable the price is what 2 oem filter are or 4 aftermarket filters so a savings all the way and the engine breaths a bit better

Can't go wrong with K&N
Great product especially for the price, reusable air filters will help reduce your carbon footprint/ cuts down on waste with the throw away air filters

My only negative: I purchased for around $100 and a couple weeks later saw the same item for around $80 so too bad that I paid more than I could have. Pros: 1. Easy to install! 2. Fit perfectly/correctly!! 3. Came packaged well!! 4. Came with stickers!! 5. Had some weight to the filter feels heavy duty!! 6. Right away I noticed it made my car feel like it accelerates more smoothly!! 7. Can be washed when needed!! I would strongly recommend this product, however I would make sure you purchase it when a lower price is available unlike myself. Thanks.

En lo personal he tenido buena experiencia con este filtro, en mi caso sí me ha dado un mejor rendimiento de combustible en aproximadamente un 3%. Además la instalación no presentó problemas. Si más adelante existiera alguna novedad la haré saber por este medio pero hasta el momento muy bien y la entrega muy rápida.
