It's the upper one seen in this pic - the other one has been sold. This is the stock ductwork that runs from the air filter housing up to the MAF on '88-'89 TPI Firebirds and Trans Ams. It is in great shape, just been collecting dust in my garage from my first TPI swap 15 years ago on my old Monte. Selling cheap at $30! Pickup preferred in Bergen County, but willing to meet within a reasonable distance.
Thanks for looking, PM me if interested!
