G35 & M35 Copper Iso Thermal upgrade

Copper Iso Thermal upgrade with Aramid gasket and Copper Throttle Body Heater. Compatible with any type of weather hot or cold, Copper Iso Thermal reduces heat transfer into your upper and lower plenum assembly, but unlike a simple bypass, the Copper Throttle Body Heater keeps only the throttle body heated to prevent ice formation inside the throttle body on very cold or snowy days. If it snows in your area use the Copper Iso Thermal for safe driving while still taking full advantage of the cold dense air for increased HP.
