What needs to be modded?
Well thats a good question. What needs to be modified to make my kit work? Lets look at the process.
First you will need to relocate the silencer for the airbag compressor. I moved mine into the compressor box to help keep it dry. So everytime my MM turns off the compressor box gets a good blow job
Next the speed sensor has to be relocated to the side of the compressor box, the wire harness for the MAF needs to be relocated to the bottom of the support bracket.
Here comes the hard part. The back area behind the headlamp was completely removed (within the engine bay). These were primed and painted flat black before I installed the kit.
I left the front section intact to prevent the filter from being saturated with moisture during a rain. You can look through and see if the headlamp was removed this would show to be a great benefit at the track.
Gotta put a high quality sealant around the opening so there is no chance engine temps will saturate the filter element.
Notice the holes straight down? Thats a good thing the OEM did to allow more air int the stock airbox. Those holes go straight down to the area behind the fog light where its WIDE OPEN.
I also had to remove the mounting tab for the OEM kit, this is done so I can keep the zip tube tight within the engine bay. Hood rub is not an issue with my CAI.
In the end it was 100% worth the effort and I'm more than pleased with the way this kit performs. I constantly show an IAT that is below ambient temps and have also killed the sharp increase of IATs at an extended stop, they are now limited to just a few degrees over ambient temp.
By design I can say it is "THE BEST CAI KIT" ever designed for the MM platform.
It's truly a Cold Air Kit!!!!
