Great! Perfect fit.
Duncan Williams, Pleasanton, California
Filter was easy to install and will be way easier to service than the OEM filter which is much thicker and hard to get in and out without taking a lot more parts off of the engine.

Mpg went up a mile or 2 and the turbo has alot more whistle which I love.
