im looking at a ex intake manifold an i was wondering if it would bolt right up and if it would do anything. i already have the si throttle body and i bored out the manifold a little bit but i just wanna knoe if it would do anything different from the way it is now. also if it would bolt up right

 

can't do it cause it's got the EGR **** on there and your ecu will throw a code. Just get everything from the head up on a EX(d16y8( head, intake manifold, ecu) and you'll be ligit.
