MHC+ BMW G80 G81 M3 OEM Style Replacement Rear Side Diffusers In Pre Preg Carbon Fibre replace the factory gloss black trim for a more premium look. These diffusers are a 1:1 copy of the standard items so that you can enjoy OEM styling in the highest quality carbon fibre.

Why choose pre-preg carbon fibre?

Unlike normal carbon fibre, pre-preg carbon is reinforced for increased strength and durability. It can also be an astonishing 70% lighter than other carbon options, ideal for weight-saving. Quality-wise, pre-preg carbon is far more consistent meaning the chance of imperfections is dramatically reduced. The manufacturing process eliminates undesirable air bubbles and results in a perfect, sleek, smooth & high gloss finish, making the ultimate part to complement your vehicle. 

When you buy pre-preg, you are investing in a higher quality, longer-lasting part that will outlast other forms of carbon fibre and potentially save you money in the long term.

Comfortable and good quality
Color: White, Size: Queen (Pack of 2)
So comfortable! We stayed at an Airbnb that used these pillows and went home and ordered some! These are similar to another more expensive pillow I’ve used but way better price. The filling feels nice and they don’t go flat or get lumpy so far.

A product that will make a difference!
Color: White, Size: King (Pack of 2)
These king-size pillows are incredibly comfortable and supportive. They are soft enough to feel luxurious, yet they provide great support for my head and neck throughout the night. The king size is perfect for a larger bed and gives the bed a full, hotel-like appearance. The pillows keep their shape well and fluff up nicely after use. I've been sleeping much better since getting them and would definitely recommend them to anyone looking for quality, comfortable pillows.

Soft...but fluffy and tall
Color: White, Size: Standard (Pack of 2)
I've only had these pillows for about a week. They are a great quality pillow. The cover is soft and seems well made. My only complaint is that they are VERY full pillows. If you're tall with broader shoulders, you'll probably love them. If you're shorter with a smaller frame you will probably feel like your head is too high and your neck at a weird angle (my problem). There seemed to be mixed reviews about softness....I would consider these a nice medium pillow. Soft filling but firm enough that your head doesn't sink to the bed. Definitely NOT a down-like pillow, so if that's what you're looking for, this is not for you.
