The issue is not the air intake to allow air into the engine. It's the air that goes to the radiator. And the answer to that is no... you need a front breather (for the radiator) if you add an aftermarket splitter because the air to the radiator is deflected upward with those vertical slats under the car in the stock configuration.
I'm working on a custom made one myself - its a pass through design by being a flat 1/4" that is gaped about 1"+ down from the front bumper nose tip. Using some 3" long bolts to make it adjustable. Its not as effective at generating down force however since it is a pass through style, its more like a wing than a splitter in function.
It is based on this one by Ikon (it is discontinued)
Looks awesome. What temps are you seeing at the track? What kind of front downforce are you seeing at various speeds?
Temps didn't change at all...
However last time I was at the track I hit a tire wall from the rear sliding around on me... so one could argue I had too much front downforce (haha)?

Never get above 210 * even in the thin high desert air at Miller, I do run a Ron Davis Radiator, No super charger but a big 434ci LS2 making a tuned 510rwhp to stay in ST1.
Front down force feels good seems balanced with the 72" wing. I designed it so its a smooth wedge right of the splitter to the radiator, kind of a wing on top of the splitter.
