I found a really big throttle body (68mm) for my elantra, and was about to purchase when i decided i should talk to someone who really knows these vehicles. So with that, i wrote to Brendan, and he said Does anyone know of any correction to this problem? If not I'll just get the 62mm.

 

he just meant that extra width is unneccesary. it will work fine. get which-ever ones cheaper i'd say... i think that too big can possibly restrict air-flow

 

68 is 2 big and will cause some HP loss... think about it ur IM can only be bored 2 a max of 61mm... therefore ur gonnaheva a 7mm Lip after ur throttle body... making the air counter flow and totally mess up the flo in ur intake... match the TB to the IM

 

yeah what he said

 

thanks alot You saved me alot of time trouble and money>
