The latest evolution of Motordyne
Engineering's plenum spacers is here...
& they're now Iso Thermal TM
The new Iso Thermal system combines our aluminum plenum spacer with thermal management components that substantially reduce upper and lower plenum temperatures. Cooler intake air temperatures increase air density, reduce the tendency for detonation (ping) and that increases engine power.
The first component is an Aramid thermal isolating gasket that is installed between the lower plenum and intake manifold. By installing the Iso Thermal™ Aramid gasket between the intake manifold and lower plenum the heat transfer is significantly reduced and both the upper and lower plenum assembly run at much lower temperatures.
The second component is a throttle body Coolant Control Valve (CCV) that allows you to 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 performance benefits.
The third thermal management component is the new Iso Thermal plenum internal supports. The plenum internal supports are self retaining and self sealing.
The fourth thermal management component is the Copper Throttle Body heater. It's an optional plug and play, set and forget component that can be used in place of the Coolant Control Valve (CCV). It doesn't matter how hot or cold the weather is, you don't have to adjust a valve based on the season or ambient temperatures. Just install it and the throttle body remains heated and the plenum remains cool.
A stand alone Motordyne Iso Thermal kit is available to previous Motordyne customers and even to those who have stock or other aftermarket plenums.
Motordyne Iso Thermal™ is the most comprehensive plenum thermal management system available. The upgrade will allow both the upper and lower plenum assembly to run much cooler.
