Handsaw took me 1 minute lol. The seal problem was the groove inside, it was not even, i had to open it up with a flat head screw driver. The corners especially was so hard to get it in.
It should, I have hood struts too, and works for me. At 8"-12" open the struts are compressed enough the hood will fall and latch. Pushing down to shut it is unsettling, would be careful not to dent it. Especially on that line in the center. Though I do not have this intake. So I really don't know how much pressure the Steeda box puts up on the hood.
Hood struts as well but I have no issues with letting my hood drop from around 8" or so and shutting.
NVM - tracked one down from S&B R0921
Not really. You can see in the pics I posted some minor discoloration near the front on the filter; this was after running a hose right into the hood vent. The majority of the water went in front of the filter and drains out the bottom of the box. Being an oil based filter helps even more with repelling water.
That's only if Steeda adjusts the fan timing like Lund does. Which I believe they leave the fan timing stock. So it should be no different than before. Lund adjusts the fan timing on all his tunes by default in an effort to keep temps in check and is matched ready for lowered thermostats. So if your Lund tuned and get a low temp thermostat the fans will come on less often.
