Air intake is the biggest restriction for the s/c so factory air box now gone 3" going in but stock throttle body is another restriction so that's next, i need to find a throttle body around 70mm that will bolt on as a direct replacement for a 1999 elantra as most so called big bore throttle bodies only give about 5mm.

you can use the mustang 65mm or 70mm with some modding. you would have to search to find out exactly what you need to do

i suppose if i have to mod i rather just get a universal billet throttle body
