I called about my intake on my 05 Dodge 5.9L Cummins. The air filter and intake tube had fixed in. Not from over tightening. K&N explained everything what could cause that. I emailed pictures and within 5 minutes I had an email back saying a new filter and tube is in the mail. They stand behind their warranties! They make great products as well. Great customer service. I will always be a fan of K&N. Use them on my motorcycles and my diesel truck. I'll recommend them to everyone I know. Thanks K&N!

I had a 2010 Dodge Ram 1500 with a 4.7 liter. I had a K&N in that and it was good. 4 weeks ago I traded that truck for a brand new 2014 Dodge Ram 1500 with the 5.7 liter HEMI! Yeah! Big difference. I got the K&N setup for my HEMI and an even bigger difference. This product made my Hemi quick, instant response and a noticeable difference in acceleration, especially on the highway. I love it! You made a badass truck badder!

This new K&N 57-series cold air intake has unleashed some serious power in my 2004 Dodge Ram Hemi..
