CSF 2014+ BMW M3/M4 (F8X) Front Mount Heat Exchanger w/Rock Guard - BlackThe S55 power BMW F8X suffers heavily from heat soak. While the ideal solution is pairing the Front Mount Heat Exchanger with the Charge Air Cooler, you can still see significant improvements with just the Heat Exchanger. The ability for the system to remove as much heat as possible is the bigger of the two weak points in the system. So if you are planning to upgrade your S55 cooling system and can only start with one, the Heat Exchanger is the right

Good quality
Model: 36 Sqft
Got it to deaden noisy furnace. Thin galvanized metal sheet feels sturdier and not flexing when blow fan started and stopped. Heavy duty and feel like real butyl material.

Great product for the price
Model: 197mil 31 sqft Car Sound Deadening Mat, Model: 197mil 31 sqft Car Sound Deadening Mat
This sound deading material has a good thickness to it. It seems like the cab of the truck is cooler inside from the heat of the motor. It’s easy to install and easy to cut with a razor blade. The quality it’s an 8/10 the only complaint I have is the adhesion will stick to your fingers if you are touching it when you peel the backing paper off. It stick to the truck great tho. It covered the entire floor and back wall of a single cab truck.

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.
