Customer Feedback

Awesome filter
I purchased your direct replacement K&N filter for my 94 Jeep Cherokee.  I noticed an increase in both performance and I am close to the original factory fuel economy again considering the vehicle has over 240 thousand miles.  The sound from the filter box has also changed, giving the vehicle a deeper roar from under the hood when I step on the gas, really gets attention.  I am also an avid off road enthusiast and just love being able to remove the filter after a wet, dusty, or even muddy day of fun in the sun and clean it right up.  I have also notice that the inside of my intake hose leading to the TB remains cleaner than before, which really is a blessing with all the dirt and dust I put my Jeep through.  Thanks for a great product and I look forward to one of your more direct airflow systems.

Have installed K&N on my last 4 vehicles: 2010 ford F-150 , 2011 Chrysler 300-C 5.7 Hemi, 2012 Jeep Grand Cherokee 5.7 Hemi, 2013 Dodge Charger SRT-8 6.4 Hemi. And I have been pleased with the performance and sound from all four.

First oil change on 2015 Jeep Cherokee 3.2 Had to put a K&N oil filter on... Right.? No problems whatsoever, didn't expect any either. Do not listen to scary forum nay sayers (oh you will have low oil pressure, it will void your warranty better use the Mopar filter) come on guys this is K&N . I'll be back for more.
