a carb. Honda has the air filter right on top of the carb. Kinda like an old chevy. Just FYI. So no company makes an intake for it... at least not like a FI intake.
I have seen custom intakes on mini-trucks before... it had like a "can" on top of the carb... and then the intake pipe attached to that. Ive heard there is a company that makes them... car/truck specific... but I have no idea where to look for them.
