K&N E-0945 Air Filter Product Reviews

Monday, November 28, 2016 - Part E-0945
I am not really happy with it so far. My mileage went down after I installed it. I am hoping this will change as it is used. I did nothing else to it and on its first trip of 400 miles my mileage went from 9.7 to 7.8. Ford E-450 V-10 Jayco RV Redhawk. If it doesn't improve I will put the stock one back in service and remove the K&N Air Filter.

I just installed current filter on our 2011 Jayco Melbourne Motorhome on an E450 Chassis w/ v10. Also have one on our 2007 Nissan Armada. They perform as advertised.

This is the best air filter that I ever owned. I love the power in my engine when I'm getting on the freeway.
