Before I installed the Vortech blower on my car I had the AFE intake pictured below. When the hood closes, it creates a barrier on top to seal the intake away from the heat coming from the motor. The only air that this intake will have access to is a factory air scoop that directs air directly to this intake.
Best of all AFE makes all their parts in their Southern California location all made in the USA, no parts are outsourced, all R&D is done in house and produced in house as well, so you can really support a great company who is passionate about manufacturing parts in the US.
AFE intakes use a very special oil base with their oiled filters, specialized and refined when AFE picked up an account to work with Toyota TRD. This oil will not gunk up your MAF and will produce a good clean signal without false MAF readings.
You can see in the picture below the access to the factory scoop will lead directly into this air vent you see in the middle of the picture
A proper intake like this one will use heat resistant materials to prevent heat soak:

Best of all they come in black, and they come in polished, and is offered at a great price. Feel free to contact me directly with any further questions
