(1) The four mounting holes are about 1/8" further outboard, so I just usead a rat tail (round) file and 20-30 minutes later the problem was solved.
(2) The mouth of the MSVT is 5" dia and your stock one is about 4.5", some CAI intake tubes may have a proble stretching. My JLT squeezed on no problem, but the reinforced connector like on my earlier K&N would not even get close and I had to improvise for a while.
You can see the 4.5" K&N coupling loosly fits inside the throat, so I had to make one from a silicne coupling I had lying around.
EDIT:
I know a lot of people have used an adapter of some kind to avoid fileing the four holes. But that adds 1/2" and can cause alignment issues with other stuff depending on your set up. The 60mm butterflies clear like a charm, no issues there at all so I prefer not to use the 1/2" spacer.
EDIT2:
The throttle body motor is a bit larger and caused a minor issue for my SHAKER where is fits over the TB. I had to do a few adjustments there too, just for any one else with the CDC Shaker.
I have the GT-500 TB with spacer on my car and it works great! I haven't tuned for it yet just kicked the timing down 2 degrees from the handheld and I still felt an increase in power.
