    slp lid modification question

    I have a 99 T/A with the WS6 suncoast creations hood and a SLP air lid. My question is, can I modify the lid to be a functional ram air box and save a few hundred $ vs buying the functional box. I know the HP gain from ram air is minimal (1 - 5 HP @ 80 mph, maybe) , so a big gain isn't my concern, just maximizing what I already have.

    The 93-97 'Birds use a different intake box that breathes top to bottom.

    98-02 'Birds breath from the bottom,our intake flows better than the 93-97 RA.

    Don't try and re-invent the wheel,do the FRA mod to the bottom of your stock intake to get the extra flow.

    This, doing the FRA will give you far better air flow the the Ram Air Mod. Only one drawl back is that you will need to change/clean (K&N) your filter more.

    I couldnt find the sticky.
    Your air filter sits in a plastic tray. Cut the bottom out leaving only the edge and the center support. Thats the free air mod as far as I know. I'll post a pic of mine later for you.
    I used a jigsaw with a blade made for plastic. Die grinder to smooth out the edges. A file would work if you don't have a grinder.
