Excellent product ! Been using K&N filters in all my motorcycles since mid 1980s, and now all our cars & trucks. Almost immediately after taking out Ford provided factory filter in my 2013 F250 Super Duty 6.7L diesel, and replacing it with K&N replacement, I saw (thru on-board computer) my MPG increase, more responsive and easier throttle control, and slightly smoother auto-transmission shifts. K&N has never disappointed me in any of their products. Thanks !

Very satisfied.

I have been waiting on this filter for a long time, I have been using a [Name Brand] filter. Changed out the filter the same day it showed up and glad I did much better filter thank you.

Fits perfect. I noticed a power increase, the turbo doesn't spoil so slow anymore. No noticeable sound increase.
Michael Wenzel, Choctaw, Oklahoma
Improved gas mileage by a couple of mpg on our last camping trip. Not many miles on our rig just yet but we were getting 9 mpg and now getting 11 mpg. The fit was good, just had to move the OAM foam over to the new filter.
