DCOE air filters

I'm getting sick of dealing with the cold air box, elephant trunk, and crazy serpentine, non-obtainable filter on my Weber 42 DCOE 8 equipped 3500 GT. I'd like to convert to some well breathing K & N units that would mount over the velocity stacks on each carb. I've seen oval looking units on some cars.
I'm wondering if anyone may have the part #s for these filters & housings? I'll keep my original set-up for the shows that matter.
Thanks, RF.
