I am doing this mod after work today. I can't wait. Thank you so much for this.
I'm excited about hopefully seeing some 1st gen kill posts on this board (even if it's just a Ford Contour).
Why don't we come up with a consensus on the best, cleanest way to go about this mod and sticky it or post it in the DIY section?
I'll let you guys now how it works on my car.
This board rocks.

I drilled holes in the airbox to let in more air, but it made way too much noise so I covered the holes with a plastic plate.
I'm talking about removing the black plastic box just before the throttle. From what I remember, this box is used to quiet down the intake noise by reducing the diameter of the pipe and diverting some air into the box. I just replaced the box with a three-inch diameter tube. Works well and it did not increase the sound.

I used a piece of wire to hold a 1/4 inch nut between the arm and the "stop". This effectively holds some secondary throttle open 24/7. I am still amazed what an improvement this has made off the line. As far as a change in gas mileage, I am not sure if it affects it negatively enought that I will remove it. I LIKE THE EXTRA POWER.

If you start from the throttle and move to the right, the intake splits into two parts. Follow these two parts to the right and they will connect to a large piece. If you look in the area between the points where the two parts connect with the large piece, there is a "throttle lever" that controls the opening of a second throttle valve inside the intake. This valve opens when the engine is at full throttle. The tweak involves placing a 1/4 object (screw) between the throttle and the stop so the throttle is always partially open, but feel free to experiment with different settings. This tweak has increased part throttle torque.

The engine that I did this mod on is the in-line 6 cylinder that is 3.0 liter displacement, naturally aspirated, standard engine for 1993 to 1997 gs300's sold in America. And... after driving with this mod for a long time, there is no measurable decrease in gas mileage.
