Installed the k&n 63 series on the 5.7 last thursday sound and performance is amazing!! I Went on a 2.5 hr trip all highway, my mpgs went from 13.3 to 14.8-15.0 and around town so far went from 11.1 to 12.5.. I went back and forth to which intake to install so glad i stuck with k&n, truely impressed. Install was easy.. here's a pic on final product

Glad to hear you are enjoying the new CAI.

I traded a bunch of college books into Amazon, and they gave me a gift card for $250.00 so this will pay for the CAI.

Any reason you purchased the 63 series? I just want to make sure I buy the right one. I also have the 5.7 hemi

Was this the exact model you bought?

Ive always been a k&n fan, the 63 series in the non CARB certified for California, provided the most feedback as well during my research. The only down fall I could find is the exposure to water from removing the lower intake box, there is a wide open space from bottom or the car right to the intake. So if you plan on wheeling you will have to modify the lower intake box which I did, or I woud also suggest the aFe ProDry Stage2, I heard lots of good things about this set up and it utilizes the lower intake box AND has a shield over the top to protect from water. Either way these HEMI's are dying for more air in and out, plus the sound is orgasmic!!!

I do not have any intentions of serious offroading. Do you think is a better option then the 63 series? do they all offer the same sound, mpg, and peformance upgrades?

I am most excited about the difference in sound. I want to hear more of that Hemi engine!!

If I could do it again, I would get one from aFe. I just like the way it looks better. I have no plans to off road my XK, but it will see a lot of snow and heavy rain. I'm sure I'll be fine, but if I was planning on doing some off roading, I would have just got a snorkel.

I will look into AFE; however, I am not sure if these are sold on Amazon. I have the credit from Amazon so I must buy it off there.

I am just concerned with the 63 series if there is a direct way for water to hit the intake. As I said I do not plan on offroading but you never know what the weather will be like.....decisions....decisions

I also got from Amazon and yes the aFe is on there
Ive heard from another member the sound and performance is good from the aFe, I cant speak directly on this.. If you want the sound, performance and mpg I got then 63 is the way to go.. If you are worried about water, let me know and I will help with the lower air box, it took me about an 1.5hrs cause I had to create and fit, but Id be surprised if it took longer than 1hr for you with my help.. at $213 shipped you cant beat the k&n.. Even if you are not planning on wheeling it, if you hit a huge puddle or something the risk of hydrolocking is huge. Message me your email I will send the pics of before and after the intake mod, I love k&n, always have even if alil work is required. Also I would find it hard to believe youd get same performance by a more enclosed CAI like the aFe but I could be wrong. Let me know if you need any help..

One I dont have a pic of is the final part of airbox mod, I attached a piece of foam cut to fit remaining gap from bottom.. I did foam because it will let some air pass but not water as much. I then sprayed everything with black Rustoleum bedliner to give a better look. This is a temp fix til I get more creative and have more time.. Very easy install for both and beneficial. Hope this helps

The mod is extremely easy, all you do is trim lower box, I will literally walk you thru the steps and where to trim as I did.. Easiest way to do it is with a dremel for clean cuts.. Let me know very easy and more than happy to help

Yes I installed intake myself, its pretty easy just follow the directions they send with intake just be extremely careful with air temp sensor. I installed and drove it for about 2-3 weeks before I realized on open it was from the bottom. After some thought and discussing with another guy on these forums we came up with the idea of trimming the lower portion of the airbox to fit, surprisingly with minimal trimming it will fit but I didnt want to restrict airflow. So I kept trimming and trimming until I got it where I thought it was good. When it comes time let me know and Ill walk you thru the trimming and where to trim
