DEI Floor & Tunnel Shiel d II-42in x 21in - 7.0 s

The DEI Floor & Tunnel Shield II-42in x 21in - 7.0 s is a professional-grade thermal and acoustic barrier designed for serious vehicle builders and performance enthusiasts who demand superior noise and heat management in custom builds. Whether you're modifying a street rod, race car, or daily driver, this heat shield addresses the fundamental challenge of protecting interior components and occupants from engine bay and exhaust heat while reducing unwanted cabin noise. Design Engineering's reputation in thermal management makes this shield an industry standard for builders who refuse to compromise on quality or performance.

This floor and tunnel shield features advanced multi-layer construction with a 7.0-second rating, indicating its thermal recovery performance under extreme conditions. The 42-inch by 21-inch coverage area addresses the critical floor pan and transmission tunnel—zones that experience significant radiant heat transfer during spirited driving or extended operation. The composite construction effectively reflects radiant energy away from the cabin while simultaneously dampening transmission whine and driveline noise, a dual benefit that transforms the driving experience in performance vehicles where stock insulation is inadequate.

Installation is straightforward for fabricators with basic welding or fastening experience, making this shield accessible for both professional shops and dedicated home garage builders. The 2.6-pound weight ensures minimal impact on overall vehicle mass while providing substantial thermal protection. This product is essential for any modification project involving upgraded exhaust systems, engine modifications, or aggressive driving conditions where factory underbody protection proves insufficient. Compatibility spans most rear-wheel-drive platforms and custom chassis applications where tunnel access is standard.
