stock intake question - Toyota Yaris Forums

ilikerice · 05-25-2011, 11:38 AM

are you talking about the rubber hose from the intake manifold TO the filterbox? or those plastic ducts under the filter box taht direct air to it?

im sure he did the plastic ducts cuz if he did the one with the maf sensor the car would run like crap..

anywho, there is no noticable hp gain. i put a aftermarket cold air intake and dyno'd it before and after install.. i maybe gained 2 hp.. so if he is just removing some plastic pieces, there is no gain.. it may however make the intake sound louder but not alot.

Yeah he removed the plastic duct. So i guess just a bit louder then. I didnt really think it would make hp difference.
