Where can I get a x flow head ? And will it make a diff?

Where can I get an x flow head from for my mk3 gti 8v and how much roughly will it set me back just for the part and would it make a big difference in performance?
Cheers Joel

 

Have a look here

 

i`ve got a crossflow head in the shed

 

Makes a reasonable difference if you fit throttle bodies whilst your there... RAM AIR

 

Why do you say that?

 

x-flow head means the t-bodies will be pointing grillward (cold air) rather then hanging at the back getting hot air. every little helps...

 

Cold air, not ram air!
