I have a 2005 Dodge Ram 4x4 5.7L Hemi Daytona Truck (the orange one). I've added in two [brand] with the stock air cleaner/housing. The sound is great just from the flows, but when I open it up at about 4800-6000 RPM it just sounded like air moving through an air tunnel with no muscle behind it. I took out the stock cleaner/housing and added in the 77-seriers and a night and day difference. When I open it up (flooring it) I get a sound that you normally only hear on a 1/4 track, lol. If your looking for a deep very mean and very aggressive sound, then you want a 1-chamber flow and this 77-seriers. Not to mention that it only took me about 10-15 mins to change it out. Very easy to do.

Excellent product
I own a 2000 Dodge Ram 1500 2WD with a 5.2L V8. I had been hesitating buying one of these air filters, mainly because it is $50.00. Well, I purchased one today and installed it. After taking it for a test drive, I could not believe the difference it makes. My engine now sounds like it doesn't have to work as hard and there is no hesitation in acceleration. Also, the rpm's when idling went from approx. 800 to about 600. I'll be checking my gas mileage over the next couple of weeks to see what kind of increase I will have. Keep up the good work.

P.S., I'll be buying one for my Buick Century as soon as I can.

I recently experienced a failure in a component of my 57-2541 Cold Air Kit after 100,000 trouble free, fuel saving miles. The problem was easily diagnosed and repaired by me at home. I contacted Elzabeth Taylor in Customer Service who was extremely helpful and very understanding in regards to my situation. She instantly shipped me a the part to replace the part that I field fixed in my driveway. She requested that I take some photos and send them to her so that Research and Developement could take a look and make any adjustments if necessary. I was delighted to comply and sent them back to her later that evening. I have K&N Cold Air Kits in my 1999 Ford F-150 and my son's 2013 Chevy Sonic 1.4 Turbo. I have an air filter in my wife's 2012 Dodge Caravan. Your products have served us well and delivered the performance figures that you quoted. Actually, I got better than quoted performance on my 1999 F-150. I averaged over 1.5 mpg increase after the intallation. I will be purchasing a Chevy Silverado with a Duramax Diesel engine very soon. I am anxious to see what we can do with K&N products at that time. Keep up the good work and the great customer focused service.
