Fitment

Universal fit. It isn’t made for one specific vehicle, so measure the area, pipe or line you want to cover and choose the size that fits.

How to Choose

  • Measure the area to cover and buy a little extra for trimming.
  • Clean and degrease the surface before applying adhesive-backed barriers.
  • Check the product’s temperature rating against where it will sit.
  • Never apply materials marked "do not apply directly to exhaust" onto exhaust parts.

Installation Tips

  1. Clean and dry the surface; remove grease and dirt.
  2. Cut a paper template, then trim the material to shape.
  3. Peel the backing and press firmly from the center out.
  4. Secure edges near airflow with ties or straps as directed.

Care and Safety

  • Inspect the material periodically for damage, lifting edges or wear, and replace it if it’s degraded.
  • Never work on a hot exhaust or engine.
  • Keep heat products away from moving parts, belts and the drive line.
  • Follow DEI’s instructions and your service manual.
