Adding a heat shield to a turbo is a very effective way to reduce under hood temperatures and increase the efficiency of the intercooler. However, heat shields are metal and absorb heat, which will eventually cause heat to effect surrounding components. 

We at GrimmSpeed decided to increase the efficiency of our heat shields even further by offering an optional, pre-cut, fiberglass-backed self-adhesive gold foil. The DEI Reflect-a-Gold™ Foil is an amazing way to take your heat shield's effectiveness to the next level and prevent it from directly absorbing radiant heat and passing it on to the surroundings. By simply applying the CNC pre-cut foil to the INSIDE of the shield, you are now creating an additional barrier for radiant heat coming from the turbo and reducing under hood temperatures even more.

The gold foil was precisely pre-designed in CAD to fit with our Version 2 Heat Shield, and then CNC cut on a plotter for perfect fit and easy install.
