unless you have a bunch of sh*t in front of it, tbh if it fits, and your temps are solid, stick with what works.
I'm working on how to engineer my afco to keep the car cooler, when I'm moving it's fine, but when the car is stopped in traffic it's definitely a problem.
Don't take my advice though, I'm actually running an afco, I didn't read about it on the interwebs.
