Great Product
(Iowa) | April 23rd, 2013
Installed on my 2005 F-250 6.0 Diesel Auto.. Easy install, uses same base mount as stock filter. Easy access to filter. Noticeable easier shifting and torque gain, a little MPG gain. Deff. get the PRE-FILTER. After one long trip you could see the dirt and other stuff it kept out. AMAZING Only other add on's I have are the Banks Duel Exhaust..
