Throttle body spacers good or bad. More power or dont do sh1t
as far as i hear, they only make a difference on large v-8's where the carb meets the manifold. but i'd like to hear if anyone on here has had a good experience with one on a 4 cly
A throttle body spacer is a cheap way of getting a larger intake manifold. Any other upgrade would be more worth your money on a prelude.
