If you get the spectre filter i believe it comes with inserts to adapt it from like 2" up to 4" so as long as you get that filter "kit" you can cut up your stock maf section and put the correct inserts in to fit where you cut it.
The filter has these little rubber sleves, you put them in section at a time till you get the right fit and then clamp it all down.
The other end of the maf tube is already the correct size and slips right into that bendable OEM boot.
One thing to note though, is once your done with this setup the maf and filter just kinda sits in there. From the TB all the way to the filter tip nothing is connected. Its just kinda flopping around under the hood. I think this is why the steeda uses that wrap around metal support/shield thing.
This is pretty much the same setup as the "stealth CAI" thing but a little louder and IMO it looks better because you get to see the new filter and some of them look really nice under the hood.
Also its gets VERY loud once you go from the stock setup to this, the engine area starts to get really loud. When you start it up and when you shut it off you now hear this loud rushing of air suction thing that kinda sounds wrong because its so loud and noticable but its just the loud intake sound.
When i did this mod to my car everyone thought i had messed something up because the OEM resonator does such a good job of muffeling it out its a big change in the sound. Oce its ideling and during reving the engine it sounds good though.
