If you compare it to dbilas then yes it can suck some hot air but if you compare it to others it has a better approach. Notice how the cone filter sits directly behind the air duct. It sucks more cold air than vflow or pflow or forge being at that position. When the car rolls the intake remains cold to the touch. If the car is stationary for a while it may soak heat, but this is eliminated once you start rolling again. One of the reasons I chose to have ceramic coating on it was to protect it from heat soak.
