What You’ll Learn (and Why It Matters)

Most factory hood liners don’t do much — they’re thin, break down over time, and offer minimal heat or noise protection. Upgrading to high‑performance insulation helps protect your paint, reduces engine noise, and keeps your cabin cooler. It’s a simple DIY project that makes a big difference.

By the End of This Guide, You’ll Be Able To:

  • Choose the right materials for your vehicle and climate
  • Install sound-deadening and thermal insulation in four simple steps
  • Reduce engine noise by 3–5 dB inside your cabin
  • Protect your hood and engine bay from long-term heat damage
  • Decide between Standard and Premium kits based on your goals and budget

Step-by-Step: How to Install

We want you give you the clearest, most efficient instructions to do it right, because we're just that dedicated to our craft.

Remove the factory hoodliner. Although you won’t need to reapply it, keep it intact for step 2. Clean the metal hood with denatured alcohol thoroughly. Getting rid of any dust, dirt, and grime will make the material stick better and be more effective. The adhesive is very strong, but we are always extra cautious when working under the hood. The last thing you want is for something to fall down onto the engine.

Key Tip
Clean well for strong, lasting adhesion.
