"Struggled a bit getting everything to fit just right ... it's crowded under the hood ... but it went pretty well and my truck had an immediate boost in power. I don't know if it will improve mileage yet, but I'll know in a month or so." —Jerry R from Ocala, FL bought a K&N Air Filters for a 2004 Ford F-350, 6.0L Powerstroke.
"This is the second K&N Air Filter I've used. The first was on my 1995 F250 diesel. I'm not a mechanic ... but when I took my 95 in for it's second tune up, at 200,000 miles the shop said the engine was in great shape. I've already noticed better performance in my new F350. I haven't checked the fuel milage yet.
I believe in preventative maintenance ... frequent oil changes and a good air filter are great insurance." —Jim R from Carbondale, CO bought a K&N Air Filters for a 2004 Ford F-350.
