Snow Screen Removed and Improvement Noticed

[MrFunk]

Snow melts... additionally, if the screen becomes blocked, the intake scoop will still pull in air from under the hood. That's why there's perforations in the top of the scoop and that's why nothing in that scoop system is exactly "air tight". Air will be sucked in via these alternate sources if that screen becomes a restriction. I think if you took a long hard look at the intake system, all of this would make perfect sense and be quite elementary.

Exactly - if the screen gets clogged with snow the engine will still get air from under the hood and other sources (it's not 100% sealed). But if the the intake/filter gets clogged then there is no other source of air into the engine. I'll probably put it back in during the winter.

The screen for sure reduces air flow - by how much I don't know - but I'd say a noticeable amount at lower speeds. Remove it for a week and see what you think. It takes all of 5 minutes and that screen is not filtering much - mine was pretty clean when I removed it. No harm in giving it a go...

Nothing placebo about it. Did a back to back drive with it in place and removed. Noticeable difference in throttle response.

I get it's super easy to remove, but it's rather subjective with the noticeable difference felt without data logged (Air mass g/s, IATS).
