I purchased the K&N 77-2570 for my 2016 Sunseeker RV and the installation instructions were very easy to read and follow. It took about 2 hours to install and you will likely need a step stool to reach all of the connections. I started the RV but have not driven it yet so no performance update yet available.

The instructions were detailed and excellent which made installation a snap. It took me about two hours to install the kit taking my time. Haven't driven the vehicle enough yet to assess improvements in performance and fuel economy.

K&N showed no products for the 2011 model year at all, but since Ford has not really changed things in 10+ years on the E350-450 V10 series, I figured it should still fit from the 2010. It did with only a plastic front plate different from the instructions. On a 5000 mile round trip from MI to AZ the terrain went from Flat to mountainous. The gas mileage ranged from 6.2 to 8.1. I believe the filter had an effect, but haven't taken this trip before and the rig was new. My old 1999 E350 Class C would do 6.9-8MPG but was slightly smaller without the intake. It does make the engine sound MUCH louder as the RPM's crank with some vibration which was annoying.
