Ok so i already have a custom intake setup that i was intending to implement, what is the best way to eliminate that big ass vacuum hose on the bottom of the OEM intake tube?? it goes to the bottom of the throttle body?? what is its purpose and is it possible to remove it or replace it with a more efficient unit?? thanks

The IAC valve is what the hose goes to underneath your throttle body.
It allows your car to idle.
How do you think your engine gets air when the throttle flap is closed? The air goes from your H-box to your IAC valve, bypassing your throttle body.
Either keep your H-box, or fabricate some sort of a reducer for the large vacuum line.

Your car wouldn't idle if you did that.

that plastic is a resonator just makes your stock intake quiter. you can take it out with no problems. atleast i did with no problems. i then took the rubber pieve that connected to it turned it upside down and ran a 2.5 inch pipe off of it to the bottom of the car didnt notice one bit of difference except things are louder but it occupied some time.mods: engine: fm stroker lightened and knifedged crank, 11:1, custom crank scraper, fully p&p head and intake mani, bored throttle body, flowed and matched stock injectors, rx7 vaf, apexi safc, gude race cams, modded ecu 8200 fuel cutoff, blaster coil, clutchmasters stage 3 clutch, fidanza fly wheel and timeing gears, msp diff, custom shortram in a cold air box
