It not only a question of the shape of the intake but the diamter and filter size. AEM has an intake designed for the edelbrock IM and throttle body package. They also can make one for you if you have a skunk2/type r (taking the diameter they have for a type R and then the shape of your car creates the intake needed.) If your upgrading your IM you should be upgrading your throttle body as well, especially on a civic since it comes with a 58mm. The question is, is it worth getting an AEM or just finding an intake that will fit.

you missing the point. if you left the stock throttle body on yes it would still fit (as long as the runners are the same). AEM has a specific intake out that fits the throttle body and intake manifold of edelbrocks. This mean the length, diamater, and filter size are made specificly for that setup. (which means a better and more smooth flow). If you get a shorter runner that means you bought a manifold for a turbo and therfore the intake is not a question since most turbo set ups come with their own intake system. You can just upgrade you intake manifold and leave your stock throttle body and intake but you best guess is do it all at once. If the intake manifold has only a little bit shorter of runners then you will have to take you intake off your throttle body and position it the amount of change (i.e. if runners are 1/2 inch shorter move it 1/2 in toward the engine and see if it will still fit). If its a short ram it won't matter much. Most aftermarket intake manifolds are the same size runner so its not a question. All the shorter ones are turbo manifolds like i said above.

Depending on the change of size in the throttle body you can still fit the same intake on the different size throttle body all you will need is a new fitting. However, as i mentioned above its better to get an intake designed for the setup because then the diameter and filter size will be changed in order to create the best flow.

Anything else?

I understand what you saying, but im not talking about leaving the throttle body stock, if you upgrade the manifold to an ITR or TR your going to do the throttle body as well becaue it wont be port matched. On the edelbrock or skunk you can leave the throttle body stock but they dont change the runners any either so its not a question. He was askign if he bought a IM with shorter runners will he need a new intake. If he's putting on shorter runners hes going to need to upgrade his throttle body anyways cuz it wont port match. So New throttle body means new intake or intake fitment

however port matching is done on the INSIDE of the TB, not the outside (before and after the butterfly) which would mean flow velocity would not be hurt as long as the tube is tapered

no bigger is good TO A POINT, if you go too large you lose all flow velocity at low RPM.....ITR is 62mm
