Product Description

The Motordyne Iso Thermal plenum spacer is a stealth modification that adds 12-14HP "under the curve" and reduces the effect of power robbing heat soak by thermally isolating both the upper and lower plenum. Its 5/16" thickness provides the best overall performance and is fully compatible with your engine cover and strut bar.

All Motordyne Iso Thermal systems keep your upper and lower plenum cooler without the risk of throttle body freezing when driving in cold weather. This is done by the use of two Aramid Iso Thermal gaskets which reduce the transfer of heat from the engine into the intake plenum. One goes between the lower plenum and intake manifold, the other is built into the spacer itself, keeping temps much cooler than stock.

Since the Iso Thermal kit has a manual coolant-to-throttle body bypass we recommend it for customers who rarely see temps below 40 degrees (and don't mind manually adjusting the bypass on the rare occasion they do). If it remains cold or snows in your area, the Copper Iso Thermal may be for you.

All kits come with everything needed for a complete installation.
