All around fairly easy
I only give it a 4 because it doesn't come with a rubber boots alloying for engine movement and I had a small dent on one end of the aluminum pipe. Other than that pretty easy, put the filter in the cold air box before installing the aluminum pipe is installed, I don't believe it will fit afterwards. Other than that sounds good runs good.
An intake that does fit '06
I ordered this intake for my '06 cummins and it works fine. There is an error on the website about the year it will fit the '06 model. It was easy to install. Don't tighten anything down until the very end. I was nervous about taking the old air monitor off the stock box but after a tug it came out in one peice. There is another rubber garment that you use to place it in the tude. One suggestion I do want to make is not to put in the tree zip ties until after the complete install. I found it impossible to zip tie things, once the intake was in and I began to zip tie things I was unable to feel where the opening was. I simply removed it with a hammer and then tied everything in a very LARGE LOOP so the tie was start then treated it into the heat sheild and finnished tightening as needed. You'll flow more air and notice an increase in turbo noise nothing to worry about.An addition note. The OEM T6 screws you will discard when done. This kit comes with replacements that are long and use an alan wrench.
Great intake!
This intake is easy to install and performs well. I've been modifying cars for a long time and AEM has been too. I decided to buy this intake because intakes are what AEM does best.

The AEM 21-8211D is considered the "AEM Brute Force" and the AEM 21-9211D is considered the "AEM Brute Force HD". AEM has engineered their Brute Force HD intakes to deliver maximum flow, filtration and durability for heavy duty applications and they even outperform the "AEM Brute Force" intakes in both dust holding capacity and filter flow.
