looks like he just smoothed it out to improve airflow...i didnt bother smoothing mine out...i just hacked a hole in the box facing the fender and used aluminum sheeting to direct cold air to the opening and sealed the factory opening grabbing hot air from the engine bay...put a polished cover over the top of it so it looked good.

never messed with the plastic ridges in the box...not enough gains to justify the time that would be spent.

hahaha nice work, but really it wont increase the airflow. (if so Toyota would have designed it smooth)

intake · 08-19-2007, 09:52 AM

it increase the airflow, that's sure.
the plastic's ridges are designed to minimize the axpiration sound, but are no good to maximize the airflow.
take them away, buy a pipercross panel filter, change the original tube with a big one and take the air from a cold area (rear the light), isolate the box from the hot engine's head and enjoy the permormance!

The ridges are designed to trap heavy particles ......like sand . Now you will have sand and small rocks "swirling" in your air box . It WILL eat a hole on your filter and it WILL end up in your engine . Basically , you just created a mini sand blaster .

^ HA. :)

Why not just cut the whole buttom of the air box to improve air flow why you are at it?

I agree.

Is there a resonator box after the filter enclosure or is it just an air-box with some tube going into the fender?

you have to be crazy to believe it.
the ridges do not trap anithyngs.
sand is not a bullet.
open your air box , look inside and give me your feedback

if you hear the pistons going up and down on your car there is something very wrong

Like a Briggs n Stratton 2 cycle?!

He wants it quiet that is understandable. I like the air-box mod.
A friend of mine did something similar to his 10th Anniversary RX7. It is simple and effective with a K&N drop-in filter.
