K&N Cold Air Intake System: Dry-Flow Air Filter, Increase Performance & Towing: Compatible with 2009-2021 RAM/DODGE 1500 Classic, 1500, 2500, 3500, 71-1561

Rotoform with oil filter. Fitment is flawless, came with everything needed for my 2013. Took 45 minutes to install. Throttle response is slightly improved, highway mileage went from 16 to 18 MPG. City mileage mostly unaffected. Intake noise is obvious when you put the hammer down but not obnoxious. Overall I’d give it a 8/10. A fully enclosed box with a cold air snorkel would be ideal but this is a great quality piece of kit.

Purchased this for a 2010 RAM 1500, 5.7L HEMI. The package and contents were all in good condition when I received it. No missing parts. Spent about 45 minutes assembling what I could without needing to touch the vehicle. Installing it in the vehicle took about 45 minutes; I would say the estimated 90 minute install time is pretty accurate. No problems with installing it per the instructions, but I did make some notes on the instructions that may help save you some time with your installation. I recommend watching the install video on the MFG website for this product if you want to know how easy it is to install!►Installation Notes• You don't need to disconnect your negative battery cable to install this kit. Just make sure the key isn't in the ignition switch, i.e. that the ignition is turned OFF. This is a lot easier than writing down all the settings, reactivating radios, etc. This step was only mentioned to prevent the engine controller from reading a fault if power was applied to the IAT sensor while it was disconnected.• I trimmed the crank case vent tube 12 inches and still wound up trimming the provided vent hose (PN 5-4015) about 4 inches in order to install it on the vent -- plenty to spare so don't worry about precisely measuring the crank case vent tube.• Recommend using a tubing/PVC cutter to trim the vent tube, provided vent hose, and the edge trim. This makes the cuts super easy, especially for the hard plastic of the vent tube, and provided the edge trim! The edge trim has a metal insert (clip) in it to help it retain its shape and bite the edge of the heat shield.• The 4mm Allen wrench mentioned in the instructions is used on the M6 button head screws only. You will need a 3mm Allen wrench (not listed) for the M5 button head screws used to assemble the heat shield.• The zip-tie provided to secure the IAT extension harness is not long enough to go around the intake tube so plan on having some extra zip-ties handy. I used four (4), 8 inch zip-ties (two attached to each other to make two bands to secure the extension harness to the inlet tube.►Performance ResultsThere was nothing truly remarkable about the this intake when I started it up after the install. However, the results were immediately apparent when I took it for a test drive. The difference in the sound of the engine when accelerating is definitely noticeable, and truly amazing! You can tell right away that she can breath better with this intake because the sound of her HEMI rumble tells you so!! There was definitely a noticeable increase in HP, which I expect is around the value of the K&N test results (+15 HP). It is too early to say how much it will improve fuel efficiency, especially since it sounds so good...it'll be hard to keep my foot out of it! From what I found doing some research, most people see a 1.5 to 2 MPG increase in their fuel efficiency.

Easy to install... literally they provide everything you need custom fit for you engine compartment... the 90 degree fitting that most people mentioned should have been included... was included in my package along with 2 hose clamps and the instructions clearly stated that if the vent hose kinks then use the 90 degree fitting and two extra clamps for this... that really shows they listened to feedback and do the right thing by the customer in my opinion.You really only need a screwdriver, I used a nut driver instead of a flathead because it is much better when your in a cramped engine compartment working on a hose clamp and your flat head keeps slipping... you'll see what I mean if you have to use a flathead. You need a set of Allen wrenches, a basic socket or wrench set and an adjustable wrench. I also recommend a PVC pipe cutter or heavy shears to trim the vent hose. The air sensor is easy to remove just don't be forceful with it and it took me about 10 seconds to remove and another 10 seconds to re-install.Overall I installed it in about 90 minutes from opening the box to taking it for a test drive... no check engine lights and worked great.As for the long term performance I will need to revisit my review after I have driven the truck more but I can say this... it doesn't change the idle sound much and I got no sucking sound from the engine... I noticed an instant responsiveness in the throttle and an immediate mpg gain when accelerating. The deep growl sound really opens up when you punch the gas and sounds like a man's truck should. No droning sounds in the cab while driving at all either.Aesthetically it's very appealing... the filter is instantly adds a performance look that I love. And not to mention one less filter to change when you do maintenance... just a light spray of oil and your set
