dang i didnt know that! You get the option on filter brand you would like with the intake system.
I have Gen2 with k&n filters and can verify that with the heat shields the intake temp runs about 10 degrees hotter then ambient temps. Without the shields installed you will see +50 degrees.
I can only imagine the Gen3 is even better
