This is for my motorhome with a V 10. Mileage is never good and power was fine. Wanted to try and increase both. Have only been on one trip since changing out filter. So a little early to have a real complete report. K & N a great product and figuired it would not hurt to help motor breath better. Have the whole system on my pickup and love it. Idea of being able to clean and reuse filter is a huge plus. Shipping was spot on for when they said it would arrive.

Tip of the Week Stop what you are doing right now and Buy a K&N air filter right now . Not joking at all , this thing added 20+ miles to every tank of fuel. I fill up 2-4 times per week so thats an extra 100 miles every 5 fill ups. Not to mention the power increase and its a life time filter you buy once and done. Check out my video review.

Replaced the stock air filter on my 2001 Ford F150 with a K&N replacement filter. I noticed an immediate increase in responsiveness and from the first full tank an increase in my gas mileage. Since this is vehicle is used more around town the gas mileage is low but I increased by at about 2 MPG. Considering a standard air filter cost about $40 per replacement this will be a financial savings after two replacements. I typically replace the filter ever 8k miles since I do some dirt road travel, this will be an easy wash and reinstall. Highly recommend these filters, should have done this sooner. I have replaced the standard air filter on my 2014 Dodge Charger with the same results and will replace the filter on my daughters 2013 Ford Focus shortly.

Love this filter. I have it on my 03 Cobra I thought about doing the whole Cold Air Intake option but the reliability and durability of these filters is top notch. I have always used K&N filters in all my mustangs ( 65' coupe, 96 mustang gt, 04 mustang v6) and have nothing but good experiences I always seen a better performing and overall running vehicle while using your filters.

I will enjoy this filter I have it in a 2007 F150, 4.6 4 door I could tell the increase when I first put it in and sure will not mind being able to wash it out every time they service my truck they say I need an air filter, not any more I have 75000 on this one an am hoping for at least that much more. Should have done this a long time ago. Thanks.
