Is there any aftermarket inlet manifolds about for the new focus st 225?

mine has cracked and id rather get a better one than fork out for the standerd one

 

take it theres no aftermarket inlets as of yet

 

Define better?

 

just generaly works better, better performance etc

basicly i have a focus st engine which im fitting in a escort. the top half of the manifold has cracked so it needs replacing. rather than replace the plastic bit id rather go better if possible.

or a carbon fibre cover insted of the plastic

 

Surely its a replace for FREE under warranty ??
