In my 91mr2 I made up an intake pipe with some plumbers pvc pipe from the hardware.i removed the airbox and all that factory boxing/piping.I then got a pod filter and made the pipework go right down into the side vent.The induction noise is absolutely awesome,it out do's my exhaust noise,sounds like a big vtec engine,i luv it.Plus you get the good ol sucking noise as well,so many people think my car is turboed.
