Front Splitters: Do They Work?

I'm collecting parts for an aircurtain, but it would be closer to Gasoline Fumes' Civic:

The duct inlets would be 'cross-eyed'.

"An air dam can be one of those magic improvements, increasing downforce and reducing drag at the same time. It can also improve engine cooling by increasing the air flow rate through the radiator. An air dam reduces drag by reducing the rate of air flow under the car, which reduces drag caused by all of the protrusions and cavities under the car. Everything that you see under the car is a drag source, so hiding that mess behind an air dam is a simple way to reduce drag."

So, I guess the consensus is that they do work. In order to protect them would you use PPF, something like a spoiler lip guard or nothing at all?

Could it possibly help reduce drag on my civic? Or just bling/downforce (i don't want an increase in either!)

That modest amount of splitter just keeps the air flow/pressure from spilling underneath the car too easily and provides a path to the sides of the car (in my opinion).

I've the done similar to the bottom of my conveyor belt chin spoiler with an attached rubber lip below it (see link in signature below).

Google picks this thread for 'splitter'.

At 5:10 he mentions that at high ride heights, a square-edged plate is adequate. At a low ride height, airfoiling is necessary.

Splitter CFD- Small Changes, 4x the Downforce (Almost)

Not sure I can give that statement a big thumbs up, I will concede a splitters side effect might be less drag. Another side effect may be less dirt/bug accumulation on the chassis. A true splitter's main objective in my world is first and foremost increased down force.
Same for a true rear spoiler, and why it originally and always has been called a "spoiler".
