We actually do have a JLT "Ram Air" Intake system that preserves the function of the shaker scoop. As far as that being cooler, the answer is no. This True Cold Air intake will actually get you cooler and higher-velocity air. The main reason being is that the shaker systems on the 2003-2004 Mach 1s do bring in outside air, but that air gets routed around the engine bay over to the air box assembly, which causes it to get warmer than air coming directly from the wheel well.
