If you have the skill make yourself a bigger intake manifold that can handle one big throttle body (one off a north star v8) and K&N style filter mounted to the throttle body. Just need a vacuum line for your map sensor. Another route would be change out your exhaust to something that lets your motor breath a little better, upsize about a 1/4 to 1/2 inch. Exhaust would be easier; I do not know your skill level with fabrication. Fastest thing that you can try would be; take the entire air box off and just mount a filter to your throttle body (Atv or motorcycle size, foam or K&N style). I did that to my Eldorado and felt like it had a nice increase in power, sounded nice too accelerating.
