The ultimate system that not only includes Mishimoto's exclusive aluminum performance intercooler, but also their performance intercooler pipe and boot kit. Fed up with high EGTs and an intercooler setup that isn't keeping up with the demands of your Duramax? The solution is finally here with the Mishimoto Duramax intercooler kit! This kit includes everything you need to improve airflow, substantially decrease air-charge temperatures, and support your truck at any power level. The first key component is the Mishimoto intercooler piping. The engineers at Mishimoto have maximized airflow by eliminating restrictive bends, resulting in a smooth and unimpeded airflow. The piping is constructed of mandrel bent aluminum, polished to a flawless finish.

For efficient holding power, this kit includes Mishimoto silicone boots with DuraCore technology and constant-tension T-bolt clamps. Mishimoto DuraCore technology is the synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. Compared to normal silicone, DuraCore provides superior resistance to heat, pressure, fuel, and oil. This effectively increases the life of the boots by preventing leaks and blowouts.

This package is rounded out with the Mishimoto intercooler featuring cast aluminum end tanks and a bar-and-plate core, all designed to allow for cool, dense air to your engine. The Mishimoto Duramax intercooler features greater core volume than the factory cooler; this provides reduced air-charge temperatures and EGTs. All the components in this kit are engineered to last, just like your truck. Offered with either a black or silver core, the Mishimoto 6.6L Duramax intercooler kit is protected by the Mishimoto signature lifetime warranty.

Used it on HVAC ductwork did its job and stuck well
Model: 197mil 31 sqft Car Sound Deadening Mat
There was a lot of material in here for the money, so a decent value, I used it for some extra sound deadening on the ductwork in my house before finishing the basement, seems to help cut down the echoes coming through the ductwork. Overall the product was good had a few pieces where the sticky tore off the foam and stuck to the paper backing but all in all no complaints.

A worthwhile addition to just butyl itself.
Model: 197mil 31 sqft Car Sound Deadening Mat
I used this as a topper to butyl sound deadening material on the floor and side panels and am very pleased. It was generally easy to use. It is very sticky and cannot be easily repositioned as the foam will separate from the sticky side if you try, but its not a big deal. I have yet to run the car but the panels are much quieter when tapped on vs just the butyl alone, and this stuff weighs almost nothing.

Easy to install and great value.
Model: 197mil 31 sqft Car Sound Deadening Mat
Very easy to cut and install with the rollers I bought separately. It adheres well even though I was installing it when the weather was closer to 40-50 degrees. Definitely helps to deaden the sound from the bare sheet metal.
