Shaving down the 3400 UIM

This is a fairly straight forward procedure.

We need to grind down the "3400 SFI" (or 3100 if you have that upper). This needs to be done so the intake can fit underneath the cowl of your 4th gen f-body and to prevent unnecessary vibrations through contacting the cowl during acceleration.

I clamped down the intake to keep it steady while I went at it with the grinder. The aluminum comes off pretty quickly.

You can see the finished product here:

Hey, I know it's ugly but I'm planning on painting it anyways.
