I have the RS airbox on my focus as well.
I was wondering what will be the impact on the throttle response for a car in the Denver area which is at 5280 ft above see level?

IMO save your money or buy a turbo ST if you want to defeat the altitude a bit.
I'm at 5,000ft-6,000ft ASL and I don't have too many issues with low end torque. Just ensure you're using 91 instead of 85.

I had first deleted the snorkel and dropin AEM filter with stock airbox, observed noticeable improvement in throttle response and low end pickup.

After a few hundred miles I added full rs airbox setup, increased the sound of intake (only above 3-4k rpm) and also observed drone at about 2~2.5K rpm while cruising in city traffic. Did not improve the performance, slightly reduced it, ambient temperature was around 100F and IAT's were 120+ around that time, I was heat soaking, so I went back to just snorkel delete + dropin AEM with stock airbox.

I am planning on 63mm throttle body upgrade and RAM air snorkel (3D printed)

63mm, stock airbox, snorkel, and airbox resonator delete works perfect.
