Interesting take, but that stock airbox is designed to keep dirt out of your engine, which is kinda important. Saw a guy hydrolock his motor after a cold air intake sucked in water during a heavy rain. Sometimes factory parts work better in real world conditions than the shiny aftermarket stuff.

Ever notice how writing stuff down makes you actually see the problem? Like my car's check engine light is on but I only looked it up when I had to tell the mechanic.

Wait, @the_piper, what weight would you expect to see? Like if a normal pour is around 8 pounds per square foot for a 4-inch slab, a 500-pound pour covering 60 square feet seems way off. Are you saying the math doesn't add up, or is the mix design way too light?
