Polished Tuned Port Injection Plenum And Runners. Condition is Used. Setup is used for trans am, camaro, corvette and firebirds. They are nicely polished. No 9th injector slot, so they could be used for a nice 9th injector delete. Only polished in the visible areas. Could use a good buff. I started to, but lost interest. I went LS instead so these are up for sale. Please ensure that they will fit your application before buying. No refunds, no guarantees and no returns. I have about $200 into these, I'd like to get as much of that back as possible, make me a fair offer and we might make a deal. Keep in mind because of the box size its gonna run at least $30 to $40 to ship it residental. Might take trades on trans am parts. Offer up guys!

Re: Polished tpi plenum and runners
It's a bit hard to tell from the photo, but the plenum looks to be the 89-92 style with shorter fins/grooves. The way to know for sure would be to look on the passenger's side rear for the MAP sensor mount and vacuum port, and between the throttle bores for the early triangular shaped port. Also the triangle port plenums have the extra passage casting on the bottom. No triangle port and no MAP boss would be 89 only. If the MAP mounting boss and provision for the vacuum port are there, 90-92.

The runners are missing the provisions for the cold start injector, so that'd mean they're 89-92 style.

FWIW, knowledge is power.
