i have a 95 accord ex, header, full exhaust, intake but im gunna buy a throttle body for it but i see 68mm and 70mm witch one should i get? and what about a throttle body spacer should i get one?

 

I would get the bigger one but there probably wouldnt be much of a difference, as for the spacer, I really dont know what this would do except maybe add a little more low end torque but it probably wouldnt really do that much, if you can find a plastic intake manifold gasket like hondata makes for the k-series I would get that as it would keep your intake air much cooler.

 

ya but you dont want to big as it will affect performance but only slighty and on the spacer it does basically the same as the tornado but no worries on it coming apart and lodgging in your intake or worse
