These FLUIDYNE heat exchangers and intercoolers are designed to keep your turbocharged or supercharged engine working at optimum levels. Larger cooling capacity than stock provides better discharge air cooling and less blower heat-soak under extended high-boost conditions. This results in more power due to the cooler intake charge. They are made of aluminum and are precision-welded for maximum efficiency and durability. These coolers use mounting tabs welded to the outer case for a simple installation.
