This fits well and my F350 2022 Ford diesel
K&N has always had good products in my book. I plan on buying another one in the future so when I pull this one out, I can put another right back in . I feel like it helps my fuel mileage.

K&N filter good investment
This is my 4th K&N engine air filter which is to say the 4th vehicle that I've purchased the product for. They are extremely more efficient than a standard disposable paper filter. Increased horsepower, better fuel mileage and WAY less expensive in the long run. I plan on keeping my pick up for many years, this is the last airfilter I'll ever have buy for it. My truck is a 2024 F350 Superduty, an OEM filter for it is $25 and needs to be replaced about once every 12 to 18 months. The K&N cost me $63 and it will outlast pretty much any other component on my truck, (at least a million miles or more). Just know that a periodic cleaning and re oiling is required about as often as you would normally change and dispose of a paper filter. The math is pretty straight forward and easy, K&N is a great investment and has a finominal R.O.I.

I have put a K&N in every vehicle I've owned for over 25 years. Trucks and motorcycles (street and dirt). I do believe the science K&N promotes... mileage, performance/increased power, etc., as they are used by amateur and professional motoesports all over the world, where every little edge can make a difference towards a win. I believe that their quality speaks for itself, as they have been producing filters for almost every type of internal combustion engine imaginable for decades. Finally, I am very much a fan of the filter's cleaning intervals. For my truck, two paper filters equal the cost of one K&N. In a dusty part of the World, like the prairies? Two filters a year, isn't unheard of. In a year's time, a K&N is paying for itself, and I haven't even had to clean it once. Hey, K&N!? Put me in an ad!! 😄😄
