Dynamat HoodLiner Sound Soaking Foam

Dynamat Hoodliner is made from a polyether urethane based acoustic sound soaker foam with a reinforced, reflective aluminized skin that is cleanable and oil and water resistant. Hoodliner has a combination of open and closed cells to accept sound waves and dissipate them. This material is 3/4" thick and can withstand -40° to 225° with 97% heat reflection.

Hoodliner Applications

The Dynamat Hoodliner is great for improving the overall sound quality in your vehicle and protecting your cars paint finish by reducing heat. It is typically used as an automotive engine compartment treatment. This kit contains one 3/4" thick 32" x 54" sheet that totals for 12 square feel of coverage.

Easy Installation

Use scissors, knife or die to cut Dynamat Hoodliner to the desired size and shape before removing the release liner. Next, remove dust, grease, moisture, and other foreign matter from the application surface. Now it’s time to peel off the release liner and start applying. The easiest way to apply is to bend the mat slightly and attach it along its shortest edge and pressing it firmly into place.

Much Less Engine Noise

Covered my bare Amigo hood with a bit to spare. Attractive product and easy to work with. Looks great and engine noise is much less. It is much quieter in the cab and my stereo sounds even better. It really seems to reduce the high frequency sounds from the engine. All the valve noise is gone. $50 well spent!

not too bad

Product is good quality. works best if applied over dynamated surface. Noise reduction is mild, but noticable. Dont expect it to sound like a lincoln, but it helps with higher frequency reduction. Applies easily and sticks like crazy. Covers pretty large area, most hoods will be fine. kinda expensive for what it is, but overall happy.

Excellent produce

I used the hood liner on my Mercedes Sprinter along with Dynamat for the doors and floor. I was very pleased with the reduction in noise and how much better we can converse in the cab.

laid back, low physical demand install upgrade, with palpable payoffs.

Headline is full of cheese, but the Dynamat hoodliner is not. its full of foam.
Like I had been advised to do, I applied some 190mil damping material to the hood as the base layer, then added this 3/4" thick hood liner to the sandwich. I have an old Jeep with a 4.0L, and well, she ain't quiet like a modern 2k era engine. the original purchaser of the Jeep clearly didn't mind the racket from the engine bay, (probably quieted it by turning up the under powered and distorted at volume radio) but I sure do! from bare naked painted metal to double material treated... the difference is noticeable even in the hood latching! quieter, no pinging or hood resonance when closing. and when the motor is running, *kisses finger like a pleased chef* ahhhh yeah.
If your hood is naked or you have some engine bay noise going on, don't even hesitate, on this. 20mins I had a template made, pieces cut, and installed. Easy peasy, laid back, low physical demand install upgrade, with palpable payoffs.
Four stars because I think the adhesive could be improved upon. aside from that, stellar!
helpful hint: get a roll of painters masking tape, a marker, and some big ol' news paper and a straight edge; (tape sheets of news paper together if needed to get the right size) tape newspaper to hood and trace where you're going to put the Dynamat and make templates of the pieces for the hood, label them! then use the templates, a hard straight edge, and a fresh blade to cut out the Dynamat hood liner to shape. Cheers!
