The throttle body bolts to your intake manifold. If you plan to replace the manifold, i'd recomend also swaping the tb. If dont want to replace both at once, go with the tb first.

 

k cool ! thanks for your help ! will my aem intake still fir the tb ? and will the tb bolt straight on to the manifold ?

Yes and yes.

 

are you replacing it for normal wear and tear, or for a performance upgrade??

My friend (with a mustang though...) replaced his with a hi-flow throttle body and got about 15 hp, I dont know if they offer them for civics?

it goes... intake(or airbox[:'(])-->throttlebody-->intake manifold-->to your engine-->exhaust manifold(header)-->exhaust.

 

yeah im doing it for the upgrade !! i found both on ebay for cheap ! but i really dont know much about this kind of stuff
