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.

Well Made Tools!
I have been installing Kilmat in my early 74 Datsun 260Z restoration and these tools are very nice for the price. I like them because they actually have ball bearings and move smoothly over the matting. The size selection is very handy as well and even has some nice finished wooden handles.

Must have
These things a freaking AWESOME!
If you're doing a big sound deadner job, you need thees! The 3 different sizes are perfect for the different shapes in the floor pans. Well built, good quality and they have a nice weight to them. Just buy them and thank me later. For $15.00 you can't go wrong.

Bringing a 1976 MG Midget to the modern world!
Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt
I've been restoring a 1976 MG Midget barn find. I bought some Sinless liner to help make the car rattle less and feel more solid.
This product is easy to cut, easy to install, and extremely sticky. I used it to line the trunk, the interior, and even some under the hood of the old MG. The adhesive stands up to the brutal temperature of the engine bay, and when (by accident) some fuel spilled onto the foam, it didn't fall apart or turn to mush.
Thanks to Siless, the MG now feels like a modern car. The floor pans feel much more solid, the doors make a heftier thud when you close them, and the trunk no longer sounds like a percussion instrument when you touch it.
If you know what you're doing, this product will transform the feel of a car. I found that 36 sq ft was enough for my MG Midget, but for a bigger car I would want more. The pattern on the back helped me to cut perfectly measured squares and rectangles. The foam itself doesn't have a strong odor, it works super well, and has held up to several months of changing temperatures (in the Midwest US.)
