The product it self was an excellent idea, but in real world applications it came up a bit short.
My Kia had an issue where the pcv valve would allow oil past it and the o rings that acted as seals between the parts would get lubricated and the parts would start to shift. When I sold the car the new owner never checked the intake and the car ran horribly due to air starvation as the air filter was saturated with engine oil. Before I put this intake system together the car was undriveable. with the factory air box was so restrictive that the car would stall and idle speeds. Once it's airways were opened up car ran great, sounded great and had way more power then stock.
