K&N Performance Cold Air Intake System: Easy Installation, Engineered to Maximize Airflow, Boost Horsepower & Torque, 77-1533KP

I'm very satisfied with my K&N performance intake. It's very easy to install and in my '04 Dodge. You can definitely feel the added horsepower and the throttle response is much better. It also gave it a stronger sound when you put it to the floor. I highly recommend this product

I purchased the 77 Series for my Dodge Ram 1500. Easy installation. The performance is out this world. More torque and horsepower and really increased the sound of my truck. The extra airflow makes aggressive sound. If you drive slower you will be able to see the fuel savings.  GREAT PRODUCT!! I will tell my friends and everyone.

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.

I had purchased a replacement K&N filter for my 2004 Ford Ranger.  After a few months driving I noticed slightly better fuel economy.  Just recently I installed a K&N Cold Air Intake on my 2007 Dodge Ram 1500 (5.7 HEMI) and all my friends were amazed that the only thing that changed was the intake.  It purs during acceleration as well as having better throttle response and a considerable jump in fuel economy.  My fuel economy gauge stayed steady at 11.8mpg (combination of both highway and city) before the installation.  Now it has leveled off at 14.4mpg with the same driving habits (as well as combination of highway and city driving) that I had before.  It took awhile for me to get over the sound and to stop punching on the gas.

2004 Dodge Quad Cab 1500 HEMI Hello, I installed a Readylift 2.5" leveling system, Flowmaster RV muffler and a more aggressive set of 20" tires, the bigger tires and the exhaust made the truck shift earlier than before which made the truck shift up and down a lot. I installed the Series 77 cold air intake system and that solved the problem. The intake sounds great and moved my shift points back to where they belong. This is the best aftermarket item I have EVER bought. ABSOLUTELY AWESOME.

I own a 2004 Dodge Rumble Bee, 5.7 Hemi, recently installed K&N 77-1533KP SYSTEM ON THE THE ENGINE, I have to to say, it really, woke that Hemi up, truck has 140,000 miles and it, seems to run better than before !!!!!!!
