DEI’s new fuel injection covers are designed to fit most factory and performance electronic fuel injectors. Available in 2, 4, 6 and 8 packs for any engine configuration, DEI’s fuel injector covers wrap around your fuel injectors and will reflect radiant heat away from the injector. Cooler fuel injectors operate more efficiently and will help prevent vapor lock and heat soak. Simple split design allows installation without having to remove the injector. Simply wrap the injector and close with built in hook and loop fastener. Universal size fits most fuel injectors.

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

We would like to introduce our new premium quality damping material. Boom Mat XL is 4mm thick and is 166% thicker than our original damping material providing extreme noise damping for the most extreme commercial and sound competition applications.

Interior panels vibrate and generate noise. Boom Mat stops that noise by trapping it between our thick, 4 mil aluminum stiffening top skin, and the asphalt free, pure butyl, noise constraining layer. Plus worry-free no sag adhesion to any interior surface, vertical or overhead, even in the most demanding of temperature extremes. Those quality components are what make Boom Mat Vibration Damping Material require only 25-50% coverage to get the job done. This saves weight, material cost and installation time.

Boom Mat out performs the competition and is the first choice by the industries top custom car builders, restoration experts and luxury car OE Manufacturers.

Use as a first layer for areas with contours and bends for vibration damping needs

Take the guess work out of thermal and acoustic control... All in one part number! Introducing a simple and cost-effective, universal-fit, sound deadening and thermal insulation kit.

STEP 1: Apply Boom Mat vibration damping material with 25-50% coverage on any flat expanses of sheet metal to remove structure-borne vibrations, squeaks & rattles. Also apply damping material to door skins for that nice solid “thud” when closing your vehicle door.

STEP 2: Apply Boom Mat Spray-On to reduce the noise from structure borne vibration in those hard to reach areas such as trunk interiors, fender wells, undercarriage, body panels, rear quarters and inside door panels.

STEP 3: Apply Under Carpet Lite over damping material on firewalls and floor boards to block up to 85% of heat transferred from engine, transmission and exhaust system while offering additional noise control.

Motorcycle Fuel Tank Cover

Motorcycle Fuel Tank Cover - 010465 - Design Engineering Inc


Just as racers use tire warmers to maintain tire temperatures between sessions, it’s equally
important to maintain stable fuel temperatures. Hot fuel results in less HP, increased fuel
pump stress, and the increased risk of vapor lock. The DEI slip-on fuel tank cover is made
from a 2mm felt backed Mylar material and is capable of reflecting up to 90% of the sun’s
heat. This helps prevent the fuel in the tank from “baking in the sun” between green flags.
Simply cinch the draw string and your bikes fuel will stay nice and cool between races. Elastic
edges ensure a snug fit, no matter what brand you ride.

  • Fast on & off, perfect for the paddock
  • Reflects heat from the sun
  • Helps prevent vapor lock
  • A must for hot sunny days
  • One size fits all
  • Won't scratch or harm tank
  • Keeps hot sun off tank & keeps fuel cool
  • Helps prevent vapor lock from high temperatures
  • Easy to use draw string to secure cover
