Makes no difference except to maximize air volume. Flow is dependant upon vacuum created from the turbo and engine pulse, CFM flow from the venture effect of the intake tube and airbox. This is restricted by the actual airbox outside inlet. Without an additional increase in air flow from the the outside inlet, there no additional cooling or increased velocity effect.
Forge Motorsport already utilizes a 4" Intake tube that interconnects with a new Turbo Inlet, which necks down to a venturi CAD designed 3" opening. It has proven performance gains demonstrated on the dyno. By comparison, I see no proven performance gains from the above Turbo Inlet Adapter. No offense intended but it's simply a means to eliminate the OEM Turbo Inlet pipe for looks alone and its additional effects upon performance or cooling are unknown.
No you can't clamp silicone over silicone and expect to have a good and proper seal that maintain intake vacuum or
CFM flow. Not something to consider or recommend in any case. High temp thermoplastic or larger turbo inlet tube is also a noneffect.
In the intakes present configuration, the SXTH Element is designed to work specifically with the OEM Turbo intake and nothing else. The transition to fit the turbo inlet has already been determined by the shape of the silicone intake tube. Additionally, intake tube length has to be a consideration. There is only so much room to accommodate the entire short ram intake assembly, within the engine compartment.
Frankly, there is nothing to gain over the present intake configuration by trying to invent a new wheel, so to speak. The SXTH Element short ram intake is not modifiable in its present configuration. There will be no performance benefit and only increased cost of the intake, to add an ornamentation which is unnecessary.

. I think you also need to see in the perspective of the N owners that don't have the Forge intake units. They want that modification too. And I wouldn't be surprised if the new SXTH intake goes all the way to the Turbocharger Inlet.
