 Great product, perfect fit.
Paul Mican, Texas
 Received the filter faster than I thought I would. It was easy to install once I figured out how to get the filter cover off my 2013 Ford F-150 with the 3.5 L twin turbo echo boost engine. I only have 12000 miles on it and I hadn't replaced filter yet. You have to lift the cover just a little then slip it toward the engine to get the tabs on the outside to pop out of their slots before you can completely lift the filter cap off the housing. I was surprised at how clean the original filter was. The K&N filter slipped right into the housing and I reassembled everything. It's to early to tell if I will get a mpg boost but everything seems to be working to my satisfaction.

 Fit perfectly in the holder. The filter wasn't as deep as the original equipment unit but I wasn't concerned about that since I knew your filter would have enhanced flow. I doubt that I will see any performance improvement but I am hoping that I see a slight fuel economy improvement. Nice product.
