Do Intake spacers actually work?




been thinking about upgrading y intake system and Black Boost is way out of my league for what it’s worth.
I've looked at I take spacers for my Weistec filters I’ve had for a while and just curious has anyone done them and do they really work or do anything or is it just hype?
I'm tuned with exhaust and Weistec drop in filters so I’m curious about real owners and not a dyno graph
