That ebay intake is garbage as is but you can cut it down a bit and replace your current intake resinator with the polished 3 in. intake tube and you will have this...
And the only piece that you have to cut off is this restrictor [ see 3rd pic ]... Which can be easily epoxied back on if you choose to go stock again. This should work for your 93.
In the attached pic [ circled in yellow ] are the ODO connector and the display mounting screws. If you have to go that far into the cluster. I hope this helps.
