"Supra's get hot, especially after some high pressure boosting. DEI products keep it cold and protects everything that the heat soak could potentially affect thanks to the wide array of thermal heat deflecting and insulating materials. Don't think I forgot "The Power of Cool" - how else could I drop my overall intake temperature 50°F without using the Cryogenic Air Intake and Intercooler Sprayer?" - Brandon Smoley, Ohio
