Thanks supercrackerbox - I can definitely make a liner for your Charger.
usetaboost - They don't deflect heat, they absorb and dissipate it. It won't be reflected back towards your intake. My aircraft firewall material is made for the aerospace industry and works phenomenally well for cars. All the info is in my blog page, the text is at the bottom and the pictures enlarge when you click them. My liners don't soak up and underhood fluids or lubricants and if they ever ger dirty they can be wiped clean with a rag moistened with Windex or water.
Liners are $85, 3 silver decals (BUICK/TURBOCHARGED/POWER 6) are $35 and Priority Mail shipping is $13 in the USA, $23 to Canada. The decals won't adhere to the original liner though because of the fiberglass material the stock liner is made of.
