Design Engineering, Inc. (DEI): The Global Leader in Thermal Tuning

Design Engineering, Inc. (DEI) has been the world's leading authority for high-quality heat and sound control solutions for over 25 years. With a mission to deliver Performance, Quality, and Support at the highest level, racers, street performance enthusiasts, and industries worldwide trust DEI's innovative products.

Why DEI Heat Protection Increases Engine Performance

In motorsports and tuned vehicles, heat is the greatest enemy of performance. DEI's products are designed to protect critical components and the driver from conductive, convective, and radiant heat.

Through targeted thermal management in the engine bay, the intake air remains cooler and the exhaust gas velocity is kept higher. The result: Less heat soak (Heat Soak), improved efficiency, and a measurable increase in horsepower and torque.

The Power of Innovation: From Titanium Wrap to Boom Mat

DEI offers a comprehensive range of solutions that can be divided into four core areas:

• Exhaust Insulation: Featuring globally recognized products like the Titanium™ Exhaust Wrap (made from pulverized lava rock) for reducing exhaust heat and protecting sensitive components.
• Reflective Barriers: High-quality heat shields like Reflect-A-Gold or Floor & Tunnel Shield for protecting electronics, cables, hoses, and the vehicle interior.
• Sound Control: The Boom Mat product line offers effective solutions for sound dampening and reducing interior driving noise.
• Cooling: High-performance coolant additives and accessories for optimizing engine management.
