Review on 😎 K&N Premium Oil Filter for 2003-2010 FORD (Super Duty, E350, E450, F250, F350, F450, F550, Harley Davidson, Club Wagon, Excursion) - Engine Protection Guaranteed! by Kevin Overturf

K&N PS-7009 Pro Series Oil Filter I have mixed feelings about this filter. Most forums say this will unduly restrict oil flow. I trust K&N and have used their products for many years and have never had any problems. Hence the mixed feelings. I haven't encountered any oil pressure issues when using this filter, but I know there will be no issues after one use. I probably won't use it again, but I'll definitely stick with the air filters. I used it on a 2004 F-350 Duperfuty with a 6.0 liter diesel. They have enough problems of their own that I don't experiment with them too much. I haven't encountered any of the catastrophic failures I've read about, but again I try not to drag things out too long before fixing problems.
