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.

Most paddocks and pit areas require fuel to be stored outside, exposing your expensive investment to the summer sun. This exposure heats the can, shortening the life of the fuel, degrading the performance potential.

Now you can keep fuel temperatures stable and extend the pot life of expensive race fuels with DEI's reflective can covers. No more stuffing the cans under blankets or moving them around all day to avoid the sun.

The DEI covers are designed to easily slip over the standard 5 gallon metal cans that most race fuels come in. These durable covers reflect away radiant heat and keep your fuel cool!

  • Fits standard 5 Gallon race fuel cans
  • Keeps race fuel cans cool
  • Easy on and off
