I remember seeing a table somewhere I think ZZP showing CFM'* with different intake set-ups and taking out the Throttle body screen seem to help our 3.8'* breath significantly better. I don't see a point to them other than to save "monkeys" from poking the MAF sensor. So here is how to remove it.
Before you start make sure you have a set of ring pliers. Look like this:
To take ring clips off that look like this:
Once you get those you can remove the screen when you get to it.
First you need to remove the back half of your air box. easily done by unscrewing it from the front box and taking off the hose clamp seen here.
So then you have just the hose like this:
The tube is just on the Throttle Body by a lip so us some fineness and pull it off by rolling it slowly just don't pull on it like an angry ape.
Now you have this scene:
Take your special pliers and fit the points in the ring clamp holes squeeze and pull it out:
once you take the ring clip out you can use a small screw driver and slip the screen out
Now that you have the screen out look and is how restrictive the screen was and how open the throttle body is.
Put your tube back on the lip of the throttle body, the back of your air box on the tube and put your two box pieces together and your set. Welcome to a freer breathing Bonneville.
