Aftermarket inlet manifolds?
 

Has anyone ever fitted one and if so, what were the results?

Corsa Veloce Inlet manifolds looks awesome and really they're expensive,which I've never seen fitted in UK,on few cars in USA or AUS I've seen them and results not sure

Cosworth Inlet manifolds people running them with good success and good results,speak to the Banny he running on his Impreza and few others


Depends for what power you are looking,but under 650bhp you should be OK with Spec C manifold,we will be running on our 2.35L Spec C manifold

If I remember correctly Lennard, you've bought a V3/4 Sti.
The stock manifold on those works fine at up to 600bhp and probably even further.
