K&N Cold Air Intake Kit: High Performance, Guaranteed to Increase Horsepower: Fits 2011-2019 Jeep/Dodge (Grand Cherokee, Durango) 5.7L V8, 77-1563KP

Looks AWESOME, sounds AWESOME at full throttle. Noticeable power increase. Super easy install. Couldn’t be happier!

Great product. I have the "NextGen" version. On a 2020 Jeep WK2, 5.7. I do notice a difference in normal daily driving. It does appear to breathe easier and I notice the sound of a V8 engine breathing now, which I was expecting and welcome. Haven't driven enough yet to notice any MPH changes I do have two things to mention: - There is an AC line that runs under the intake tube. The K&N intake is now resting on the AC line. I think it will be ok. I probably wouldn't substitute some change in the pipe to accomodate the line (potentially affecting performace) just so that it's not resting on the line. But worth mentioning. I suspect they might not of had the clearance to make the pipe curve around it - at least not without making the tube narrower. - This is 100% my fault - but the new 1/2 hose for the crank vent to me looked too long - and it was long enough that the bend was causing a leak. Simple solution I thought -- I'll just cut the hose a little. I took about 2in off and now the pipe is too short to fit where it needs to so that the engine cover fits on. I assumed they just gave a little extra just in case... My bad. Luckily it's a simple/common hose. I can likely get it here for $5-10 I have used K&N filters in many vehicles. I have not used their CAI before. So far so good.

Bin sehr zufrieden mit dem Fillter. Hat einen kernigen Klang wenn Leistung abgerufen wird, und hält sich dezent zurück beim cruisen. Anbau ist kein Problem, passte alles. Natürlich ist die Optik super. Ob es eine Leistungssteigerung gibt kann ich nicht sagen, oben rum habe ich aber das Gefühl.

First, I installed this on a 2018 Grand Cherokee Limited Sterling edition with the 5.7L equipped with the tow package. I have also installed K&N intake systems on at least 6 other vehicles over the last decade. As expected the fit and engineering is very good. It took less than 20 minutes to install - in part because there are not many factory mounting points and removal of the stock intake system takes about 2 minutes. After installing I took it for a 5 mile test drive - mainly to see what the noise level is. I was surprised how quiet the K&N system is for this vehicle. Probably the quietest intake I have installed to date, and it only has a slight grumble at full open throttle above 3,000 RPM. That is a good thing - my wife rolled her eyes when she saw the box arrive, and at idle and normal acceleration is really isn’t much louder than stock. Throttle response is slightly better and I have no idea if I’ll see an increase in mileage, but I’ve actually been happy with the 19-20 we have seen in the first 1,000 miles. As others have mentioned, be careful with the air sensor - it’s fragile but as long as you remove and replace by hand you will be fine. There is a metal coolant line on my Jeep that runs under the intake - I had to bend the bracket on the line to allow it to clear but you can also fine tune the angle of the intake tube before tightening the fittings on both sides. Looks great and I like the reusable / washable filter. I’d buy this again.

The intake installation was a breeze. If you have the tools you need (8mm and 10mm sockets, ratchet with extension, 9/16 wrench, pliers and scissors/sheers), you are good to go. It took me about an hour between locating tools, reading directions and installation. If I had to do it again, should take 20-30 minutes now. The sound it makes now is awesome. See the before and after video I attached. The only issue I have is that I do not see a big 17bhp advertised gain in horsepower. But there surely is some. My 2012 Durango used to do 0-60 in 7.2 seconds when it had under 20k miles on it. I have a YouTube video of that. Now that it has about 70k miles, it was doing about 8.2 seconds. After I installed the intake, I see about 7.7 seconds. So, I recovered about half of the lost horsepower I had lost. I am happy enough with that. The best part is the sound it now makes and the RPM goes up much faster. Maybe a tune up will help. I also see some gain at higher speeds, but I don't have a quarter mile run numbers from my OEM intake. See Before/After pictures and video.
