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.

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.
Damplifier Pro™ is a superior sound deadener great for deadening the vibrating metal, allowing you to have a clearer, crisper sounding engine. Even more than that, Damplifier Pro™ is excellent at reducing heat transfer at 100% coverage, a major problem for more powerful engines. Our box with 13.5 sq ft of material is all you'll need to get the job done right.
Key Tip
Use a handroller for around dips and divots.
Use the existing liner to create an outline to cut your heat insulation material to size using a utility knife or scissors. Your hood will need anywhere from 12-20 sq ft of material depending on the vehicle you have. The kit has two options based on how much room you have and how many divots your hood has.
Key Tip
Choose the hood insulation that fits your vehicle and install preference.
Tape up all seams and edges with a high temperature foil tape, this will help keep everything in place and keep the edges from fraying. This is an especially important step for extreme heat use cases. Use any clips or fasteners under the hood as additional support for your insulation and/or heat shield. Better safe than sorry!

Very good quality product! It was a slow process getting the Damplifier Pro cut & pressed into all the contours on the the underside of the hood, but when it was all done, it definitely cut down the aggressive noise level of my very non-stock 7.3L Powerstroke. Helped inside & out!

If the factory liner is sagging, brittle, falling apart, or missing entirely, it’s no longer effective. Years of engine heat can also reduce performance even if it still looks okay.
Hood insulation helps reduce high-frequency engine noise and mechanical clatter escaping upward. It won’t silence the engine, but it does smooth out harsh sound.
Mega Block is a better sound absorber and has a higher R-value per inch than Heat Wave Pro. Mega Block also has a peel & stick backing while Heat Wave Pro requires an adhesive. Heat Wave Pro is still a high-performing product, and shines best under hoods with a lot of turns. Mega Block works best on flatter hoods.
You’ll need a denatured alcohol or a mild degreaser, a utility knife or heavy scissors, and a small roller for pressing the deadening material into place. A T-square can come in handy too.
Start by removing any loose or damaged factory insulation. Clean the underside of the hood thoroughly so it’s dry and free of dust, oil, or residue—this is key for good adhesion and long-term hold. Once clean, you’re ready to measure, cut, and apply the insulation.
