Thanks for this tip!!
I used an Xacto knife, and labouriously trimmed each tiny square. It seemed like a good idea at the time, and it certainly extended my beer-drinking

I figure my vent-squares were 70% blocked by lousy molding. Trimming went easily.
The difference was very noticeable, say after work. Incoming air was no longer noticeably warmed. Nice!
However, if I park at a store for a few minuts, something seems to get heat-soaked. Then, the incoming air is warmed up, just as it was before

So, under "hot-restart" conditions, I still have to run the A/C for a minute or two in order to eliminate whatever heat-soaking is happening.
Overall - I like cheap mods like this.
