butterfly valves
hey i was wondering if you guys knew where i can find a bigger butterfly valve for a bored out throttle body. and also what do those 4 butterfly valves on the intake manifold do? are they just for emissions or are they there for a purpose? thanks

It's called the IAB (intake air bypass) or dual stage intake manifold. Read the FAQs or search it.
