the egr plate completely blocks off the egr from the intake manifold. my exhuast manifold doesnt have a bung for and egr tube so i took the tube and just bent it in hopes that it would close it off... well it really didnt so i would get ruff starts but after the car warmed up it would drive fine (i guess because when you start the car the egr is opened and i was getting fresh un-metered air into the engine hence why i was getting lean afrs... but then again im just guessing)...
you can buy it here

another alternative i guess would be to find a bolt and block off the tube side..
installing it was fairly simple from under the car...
pros of blocking it off? well its debatable but who want hot exhaust gases being recirculated back into the intake
oh yeah... the corksport bronzeoil shift linkage bushings are worth it... even though i was only able to use one pair... now my TWM SS really feels like a short(er) shifter... nice and tight and crisp... highly recomended
