K&N intake for the 4.7: a review

I installed a K&N intake on one of the 4.7L Commanders this weekend for a fellow member. What a pain in the @$$!!! The instructions are very vague. The pictures showed a Grand cherokee with parts that don't even exist in the Commander. I even had to modify a few things to make the intake fit correctly. Two hours later, we finally got it on and made the engine sound mean.

If you're planning on doing this install I suggest test fitting the heatshield a few times before you tighten everything down. It's a little tricky if you install all the brackets the way show in the pics. Take your time and use a little common sense and imagination if you have to. Also, there is no T-fitting for the crankcase breather tube as described in the instructions. You will need to cut about 5" off of the existing crankcase breather tube to allow it to connect to the new intake. Then you should be in business. I'll see if I can get some pics of it soon. I forgot to do that this weekend

I ordered the AEM Brute Force cold air intake for the 5.7L Hemi last night. I hope my installation and manufacturer instructions are easier than your experience. I will post pictures and evaluation remarks later this week.

Re: K&N intake for the 4.7: a review

Do you have a link to that intake? I'd like to take a look at it for comparison.

Re: K&N intake for the 4.7: a review

They don't show any pictures for it yet. They only have an intake for the HEMI commander. The 4.7 and Hemi intakes are slightly diffrent.

Anyone check out the AirRaid kit yet for the HEMI? Still trying to decide whether to go the metal or plastic route.

INTREPER did the install on my Commander and he is dead on in his explanations!!!!

He did a great job and although we run into several minor roadblocks during the install, INTREPER got it all to work....thanks again INTREPER!!!!

Re: K&N intake for the 4.7: a review

Out of curiosity, K&N or the other filter, what does this do for the Commander? Performance wise? I know it's not necessary but does it make a whole lot of difference?

You can definitely tell a difference in the acceleration/horsepower. When I give it gas, it does not labor at all up any hills or wherever. It has added quite a kick to my engines accelaration power.

As far as gas mileage improvement, I really haven't noticed any significant improvement...yet. I drive 80-90% city miles, so I am not sure if I will notice much improvement like I was hoping for. But, I just got it installed only a week ago, so time will tell.

I will report back after a month.
