Dinan Turbo Inlet Pipe - 2016-2021 BMW M240i/340i/440i
Turbo inlet pipes serve two very distinct, and differing, purposes. On one hand the optimization of a turbo inlet pipe will encourage better turbo efficiency and responsiveness by allowing the turbo to ingest more air by way of an unobstructed and larger volume flow path. On the other, you have a more visceral benefit that some may argue is equally, or even more, important than that of efficiency/flow optimization --- increased sound. No matter which of the distinct purposes is favored, Dinan will deliver on both.
Features:
- Increased turbo efficiency and reliability courtesy of maximum unimpeded and uniform airflow.
- Eliminates the factory sound resonator for increased turbo vocalization.
- More Flow: Up to 24% greater than stock.
- 24% increase in overall volume over OEM inlet.
- Average of 10.8% larger internal diameter throughout (maximum cross-sectional area allowed).
- Carbon fiber construction for increased durability and visual appeal.
- Direct replacement of OEM turbo inlet.
- Quick and easy bolt-on installation.

Affordable, Clean and does the job.
Size: 36 sqft, Size: 36 sqft
I consumed about 90% of this box doing all doors and the tailgate on a 2000 tahoe. I applied it very liberally inside every door (exteror) panel. We then added an almost equal amount of deadening/absorbing/decoupling foam to the other side of the door (panel side). If you know how many rattles a circa 2000 tahoe GMT800 can have by now, you can appreciate why I added this as a "must" if i were to put some money back into this vehicle. Best sub $150 spent on this mini resto so far, right next to tint.
Good quality. Not to thick or thin. Good sized sheets. Seamed to deaden as good as another slightly thicker material i recently used in my F250. My box was delivered with no issues of melting or anything funky. Clean, no major smell before or after and easy to work with. Maybe buy a roller set and wear gloves. Save your hands if your doing inside of panels. Good buy. Will buy more for future projects.

AS GOOD AS ANY OTHER, WORKS GREAT
Size: 36 sqft, Size: 36 sqft
Used this in my 17 RAM 1500. This stuff works great, just as good as S...ss brand that is also sold on here. Same thickness and same tackiness. And this stuff sticks like crazy, once its laid down and rolled onto the surface, it is hard to remove, so I am pretty sure it will stay where I installed it. It is great value, one box was enough to do the whole roof of the truck with a little left over for small spots. I think it took a total of 2.5 boxes to do my whole crew cab, roof, floor and back wall and most of the firewall, and I also added a layer of their .25" foam. I do notice a difference in less outside noise, from wind and road. I will be doing my wife car soon, and this is the product I will be using again, I recommend this.

Dyna... who?
Size: 36 sqft
This stuff works great. Fraction of the cost to Dyna.. and just as good. Very sticky. Used in doors, floors and ceiling. Great product and performs flawlessly. I would highly recommend this.

Awesome, inexpensive alternative to name-brands!
Size: 36 sqft
Awesome. Stuck well with alcohol prep and time to let liquid flash-off. Very consistent, piece to piece. Backing peeled easily when desired. Compared to Amazon Basics, the butyl seemed a little thicker (infinitesimally) and stickier, foil was less thick than Amazon Basics. Very good value. Started with my nice car, but after completing project, sound dampened all cars in the immediate family it made such a noticeable difference in sound level and quality of music from soeakers. Recommended!
