I have not cut out that area behind the Sidemount to improve airflow efficiency. Since my SMIC is practically next to it, I would imagine a significant improvement if I cut out a hole and replaced it with wiremesh.
For my Dejon smic, I replaced that entire plastic piece with two layers of 1/4" hardware cloth, overlaid at a 45* angle to one another, mounted about 1.5" from the back of the core. Keeps all but the smallest pebbles from getting through, and it flows great.
Before I did that, I put a couple of spacers between the core and the plastic inner fender. I made them by cutting a 1/2" long piece of 3" pvc tubing (so I had a skinny donut shape basically), and zip tying them to the plastic. Ghetto for sure, but it got some air flowing through the core, as opposed to just trickling through.
