"Have been running for about 4 weeks and have noticed better
acceleration response so far. The gas mileage is a little hard
to gauge, but has been as good or slightly better than before
installation. The installation fit is very tight and takes a few
tries to get it to seat properly." —Bill K from Anaheim, CA bought an aFe Pro-Guard 7 Air Filters for a 2008 Ford F-350, 6.4L Powerstroke.
"Very easy to install. High quality product from K&N. Installed on a Ford V10." —Arturo M from Potter Valley, CA bought a K&N Air Filters for a 2008 Ford F-350, 6.8L V10.
"I purchased this to replace my stock air filter and it definitely flows more air than stock." —Ryan H from Ellwood City, PA bought a K&N Air Filters for a 2008 Ford F-350, 6.4L Power Stroke.
"Great experience from previous K&N Filters. Hoping this one will do the same." —Robert B from Smithfield, VA bought a K&N Air Filters for a 2008 Ford F-350.
"Having only stock air filters during my 49 driving years I definitely can feel the difference the K&N has made in acceleration on my F350 Super Duty. The engine is quicker to respond to a tap on the accelerator, with more get-away power. As for mpg there are so many variables in towing a heavy 5th wheel toy hauler I can't really tell any difference yet. The transmission doesn't shift down as much on an incline as with a stock filter. I am happy with my purchase of the K&N air filter. Easy install." —Jerry D from Piketon, OH bought a K&N Air Filters for a 2008 Ford F-350.
"I have been using k&n filters in all diesel and gas vehicles I have owned for the last 20 years.Nothing better for intake without replacing your whole system." —Roy C from Forest Lake, MN bought a K&N Air Filters for a 2008 Ford F-350.
