Iso Thermal
1) The first component is an Aramid thermal isolating gasket that is installed between the lower plenum & intake manifold. By installing a Motordyne Iso thermal Aramid gasket between the intake manifold & lower plenum, the heat soak is significantly reduced.
2) The second component is the throttle body Coolant Control Valve (CCV). The CCV allows you to selectively heat (or not heat) the plenum assembly. With local weather temperatures below 55'F the valve is left open. In warmer weather the valve can be closed for maximum thermal benefits.
