Ultra 47™ Turbo Shield

DEI Ultra 47™ Turbo Shield - 010172 - Design Engineering
DEI Ultra 47™ Turbo Shield Kit - 010173 - Design Engineering

Made from a tri-layer mix of an Aluminum impregnated glass fiber outer shell with a hi-temperature insulating mat core and silica glass blend liner. Double stitching and heavy duty capped anchor points make the Ultra 47™ Turbo Shield look great and perform even better. Keeping the exhaust heat in the turbo housing reduces turbo spool time and increases exhaust gas velocity resulting in more power quicker. Available in T-3 and T-4 Turbo sizes with more to come.

  • Quicker spool up times
  • Reduced under hood temperatures
  • Increased exhaust gas velocity
  • Smooth capped anchor points
  • Made in the USA
  • Available as SHIELD ONLY or in a KIT

Each KIT includes:

  • Ultra 47™ Turbo Shield
  • 2" x 15 ft roll of black wrap
  • Two 20" stainless steel Locking Ties

DEI ONYX Series™ Pipe Shield - 010496 - Design Engineering Inc

DEI has launched the next generation of heat protection performance! Using a combination of advanced textiles, DEI developed a flexible heat shield solution that looks great and outperforms other conventional heat shields available today. This enhanced performance starts by joining two durable materials together forming a dual-layer design. The outer layer is made from heat-treated glass fiber that is bonded with molten aluminum and then formed into a tight weave for durability and strength.

The inside material is made of a specially treated, high temperature resistant fabric (89% silica) designed to withstand some serious exhaust heat. The outer edge is finished off with a surge stitch for durability. All hardware is stainless steel. The result is a product with very good thermal performance up to 1350°F, with an eye catching rich black finish.

Turbo systems are the easiest and most cost effective way to add horsepower to engines in a big way. DEI recognized the need for new Turbo Shield applications, and now offer Turbo Shields in the smaller turbo sizes. Building on the popularity of the ONYX™ Series, DEI has expanded its turbo shield offerings to include a GT 22 and GT25 sized shields that utilize this high performing material. Unlike cheap, knock-off copies, the DEI Turbo Shields are Made in the USA, using an exclusive combination of premium heat resistant textiles and newly designated stainless steel attachment anchors. DEI Turbo Shields are used to maintain a more consistent temperature in the turbo, increasing efficency and decreasing turbo lag. In addition to Garret® brand turbo housings, the Onyx™ Turbo Shields will fit several other popular turbo brands including Mitsubishi® and others.
