Call me stupid

what you have to remove is the air silencer tube. Here´s how to get to it:

1. Remove the top of your airbox (the thingamabob behind the driver´s side headlight that holds the air filter) there should be 4 bolts or screws holding the top on. (there also may be some wires plugged into the top of the airbox, unplug them).

2. Take out the air filter and remove the bottom of the airbox. There should be 4 bolts holding this in place. Once you remove the filter, you will see a hole at the bottom of the airbox (this is where the air tube silencer connects to the air box.) Remove the bottom of the airbox and you should see the silencer tube. There is 1 bolt on the chassis of the car holding this in place. Remove the bolt and remove the tube.

3. Reattach the airbox and your done!

Thank you dood

no prob, let me know how it turns out

So are you saying that you have the bottom of the filter "sticking out" the bottom of the air box? or is that cutting too much off?

yeah, so basically the filter is the size of the hole...but leave enough of the box so the filter wont fall through.

yes, i´m bumping this post back up...
so even after these air box mods, can you still replace the box with a conical filter? and if i intend to go conical, what dimensions of the filter should i get that would fit the adapter for the MAF sensor n such? (93LX)

Here´s an interesting note. I dont have the turbo installed yet, but I do have my boost gauge in and reading vacuum.

With my airbox cut mod, at 80mph with the K&N filter at full throttle I can actually read .5psi of boost. Must be acting like some sort of ram air with the box cut and sitting above the tranny.

welcome to the world of resonant frequency. you are experiencing the same effect that velocity stacks provide. the moving column of air is just the right size and as the valves close it creates a pressure spike. these are not always good. when there is a spike in one place there is more vacuum in another.
