K&N High-Flow Original Lifetime Engine Air Filter: Increase Power & Towing, Washable, Premium: Compatible with 1995-2017 Ford (E150, E250, E350, E450, Mustang and other vehicle models) E-0945

drop-in fit, and made my truck breathe obviously better. I have not calculated the increase in gas mileage yet, but it has been noticeable.

Simple five-minute install on our Class C Motorhome on top of a Ford E-450 Super Duty 6.8 liter V-10. I have used K&N filters on every car and truck I've owned for the last 25 years and have been extremely pleased with their performance, and ease of cleaning and reuse. This air filter is a unique type vs the more common flat filters, but nonetheless, it was a phenomenally easy replacement for the existing paper filter on the RV we purchased. Together with an oil and XMSN oil change and K&N Oil Filter, our engine in now purring, with more pep, and I expect to see an increase in MPG. When you're getting ready to take an RV on a more than 4000 mile road trip, it's important to have everything perfect before departure to mitigate the potential of breaking down in some inhospitable or remote location. K&N gives me the warm, fuzzy feeling of knowing that I have the best installed! Five Stars and an honest and very hearty recommendation! *If you found my review helpful to you, please let Amazon know by clicking the "HELPFUL" button below!

I have been using K&N air filters in my dirt bikes since the mid 1970's. I have used them in everything from Honda Elsinores to Jeep CJ's, Yamaha YZ's, Jeep Cherokee's, and now my F150 and my daughter's Dodge Avenger. K&N is a great value, not only in increased horsepower and better fuel economy, but also it is servicable and lasts a lifetime. Improved performance, less maintenance, better filtration, lasts forever, fits perfectly, installs easily. Buying a K&N filter is a no-brainer.

Works like it should

I have noticed greater pullling power up steep grades with my 2002 motor home that has the 2valve v10

Okay, I finally cleaned this thing, 2 years/50k miles after installation. I drive a Ford E350 Van with a 6.8Liter V10 engine, converted to 4x4. I've made numerous trips from the San Francisco area up to Vancouver, Idaho, Death Valley, Utah, and to burningman (one of the dustiest places I've been). After last year's burningman, I did have to stop on the side of the road and beat out a huge pile of dust from the filter; my car was barely able to make it over the mountain pass to get back home. After beating the dust out (it left a huge pile), the car ran perfectly again. Other than that, it's been ~50k miles since installed. Tonight, I gave the filter it's first cleaning. The inside of the filter looked as clean as new. However, the outside of the filter was a disaster. I used the K&N cleaning kit. After the first cleaner process, and running water through the filter (I did it in the shower), 5 minutes of running water later, and it was still a solid brown river going down the drain. And there were several dozen huge insects (bees and other things) in there, too. But the inside of the filter was clean, and the car's been running fine through all this. A winner in my book. I will try to remember to clean it yearly, now, though.

Better than disposable filters and you can clean as often as you care too to have top performance

Also, less throttle is needed on the freeway, which should mean better fuel economy. A little harder to install because the K&N gasket is made of a stiffer material than normal filters. I have a 2001 Ford Econoline 150 with the 4.6 V8. When checking out you have the option of an outer box; I didn't choose that and my filter arrived in a bag, slightly crushed... I also got a panel style K&N for my 1.9 BMW Z3, and the difference was even more dramatic, like adding a turbo.

Se instaló en Ford Lobo Fx4 v8 4.6 Lt 4x4, se reemplazo el filtro OEM K&N de reemplazo, se instaló y si se mejoro la respuesta del acelerador, contra filtro anterior K&N remplazo

I've put a k&n engine air filter in every vehicle I've owned and again not disappointed. Was slightly tight clamping it back into place but I only saw that as having a good seal around the rubber part of the filter. I doubt it gives you extra horsepower but I've noticed better throttle response. I'll continue to use these k&n filters in the future for any other vehicles I may purchase.

Good price. Easy to install.

Le quedó perfecto a mi camioneta!
