The delete

The WRX has a set of butterfly valves in the inlet manifold (well, strictly the bits that sit between the heads and the manifold.
A TGV delete is essentially removing these and modifying the casting to remove a load of metal. Supposed to give a bit more power, but requires mapping. Done as part of a series of mods, it might be worth it, but I wouldnt' bother if you're still fairly standard.

The actual manifolds are the same bar the colour
It's just the tumblers you will need
But probably easier just to buy a whole Sti inlet setup from a breakers like scoobyspares
And as above it will need mapping so do it with a few other mods to get your money's worth
