Thermal & Acoustic Interior Kit

Boom Mat Thermal & Acoustic Interior Kit - 050500 - Design Engineering Inc
Boom Mat Thermal & Acoustic Interior Kit - 050500 - Design Engineering Inc


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
