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.

wash carefully
Size: 38F, Color: Sargasso
Loved this bra so much that I immediately ordered a second one, but the wire broke through on the first wash. Still love it and will probably repurchase again because the fit is perfect, but if you're like me and just throw your bras in with the rest of your clothes, be sure to wash them on a delicate cycle! Other than that this is a fantastic bra. Good price, true to size, looks great and is super comfortable!

Ordered 3
Size: 44C, Color: Black
Great bra, pretty true to size, comfortable. Ordered one in fall and tried several other name brand underwire bras (lane bryant, Victoria Secret, Bali, Torrid, Hanes), returned most of them and came back for two more colors of this brand that I’d never heard of before. The material is nice, they fit well, I wash in cold on delicate and hang dry: so far so good. I normally take a 42C and went 44 for these. I think a 42 probably woulda been ok (I’m on the middle hook) but someone said they ran small. I’m not sure of that but keep it in mind if you’re maybe between sizes.

The BEST BRA for big bewbs!
Size: 36G, Color: Black
I've been a fan of Delimira for a while - it's hard to find a well made, comfortable, breathable bra for larger cup sizes at a price that doesn't require taking out a mortgage to afford it.
I love this bra. It fits well, it's comfortable, it doesn't get hot, it seems really durable, and it's...sturdy. The underwire is not annoying, and while it's not the cutest bra, it's also not the most matronly bra I own. I have it in all three available colors and will 100% buy more colors should they ever release them.

Didn’t last for very long. Comfortable
Size: 42DD, Color: Beige
Comfortable bra. Good price but the wire popped out on one side after about 8 times of wearing it. Maybe it was the way I laundered it. It’s comfortable enough to want to order again and test that theory.

Love love love this bra.
Size: 34E, Color: Beige
I dont really write reviews but really felt like I needed to hop on here and give one. I have a terrible time finding bras that fit (small frame and my boobs never shrunk back down after having kids). I was initially looking for a non-underwire bra and ordred a couple to try. Was annoyed when this came in having underwire but thought ok, well its here so may as well try it. Fit like a dream so I told myself, Ill wear it for an hour and see how I feel about it then. I totally forgot I was wearing it. It is SO comfortable. The back doesnt ride up, I dont have underboob, it breathes nicely, holds me up, straps dont dig in or fall down, and I dont feel a huge sense of relief after taking it off at the end of the day. Ive ordered two more and after a few weeks of wearing and washing a couple times, I still absolutely love it.
