This premium stealth modification adds 1HP-2HP and reduces the effect of power robbing heat soak. Motordyne Iso Thermal is the most comprehensive plenum thermal management system available. The upgrade will reduce heat transfer into the upper and lower plenum assembly. This helps to reduce power loss as the engine becomes heat soaked. Compatible with any type of plenum stock or modified. Recommended for warm climates generally above 45deg.F.
