It's a plastic cup from a thrift store, and has been there for over 2 years, with no problems. Yes, it's ghetto-fab, but proven to work.
Here's what I did:
Bought a microwave safe cup with the mouth being the same ID as the OD of the MAF (The longer the cup, the smoother the transition).
Took the peice out of the accordian peice that the small hose plugs into, and drilled a hole in the cup for it to fit snugly into and pushed it through from the inside.
Cut the small end of the cup to match the TB outer diameter. Put the small end in boiling water for a few minutes to soften it. While it was soft, shoved it onto the TB for an airtight fit. When cool, hose clamped it.
Hose clamped the small hose onto the peice sticking out.
Hose clamped my MAF on.
Obviously, you're not going to gain that much, but for a few minutes, and 25 cents (or free), it's worthwhile! Plus you can find one that matches your color scheme.
If you're afraid that it won't hold up, you can get a stainless steel cup. I was going to, but this has worked fine, even driving thousands of miles in 100+ degrees in the desert, and through sub-zero snowboarding adventures.
