Got everything installed the other day.

Used junkyard Dinan CAI
New Dinan filter
generic(VW Mk4 aluminum aftermarket) 4" Maf, I painted it satin black
Two generic 4" silicone couplers for each end of the 4" Maf to mate with the Dinan intake and stock 4.6is intake elbow.
N62 big bore throttle body, with adaptor wiring harness
breather filter(since the junkyard CAI did not come with) bought at parts store.

No alterations needed to the stock intake elbow from the 4.6is in order to adapt the bigger bore items, other than trimming the maf entrance a bit to fit to your chosen 4" maf and silicone coupler.

Installed and is (air)tight as a drum. Getting stage 4 Dinan engine and trans flash tomorrow. Car runs fine as is, but you really shouldnt push it hard(running it lean) and scramble all the adaptations as it could cause issues with your ecu, or worse -- engine wear, without having the appropriate flash... no big deal if its just the CAI and stock maf and TB.
