how many "mm" is my JDM b16a intake manifold?
 

I have a 95 honda delsol DOHC vtec JDM B16a I was wondering how many mm is my IM. cuz i seen intakes on ebay that are 65mm but i want to make sure that mine is not the same size. And what are the gains of putting a high flow IM ?

What do you mean you want to make sure yours insn't the same size? The purpose of an intake manifold is to be less restrictive, and let more air-flow in to the motor. If you're replacing just the manifold with out any other mods, Id say maybe 7-10hp at the crank.

i kno the bigger the opening the more air. but i was tring to say i want a 65mm opening but if my stock IM is the same why should i buy the new one. But i think stock is like 60mm but i'm not sure, thats y i'm not buying the other IM

I see, well Im almost a 100% sure that the after market manifold opening would be bigger, and also, aftermaret manifolds are designed to be less restrictive than stock either way.
