CSF BMW F8X M3/M4/M2C Auxiliary Radiators w/ Rock Guards (Sold Individually - Fits Left and RightCompared to the OEM F8X coolers, the CSF units are a significant upgrade. CSF eliminated the OE plastic mounting pod by incorporating it into the modular design that fits both sides. This design improvement increases the size of both the core and tanks. The extra space taken from the mounting pod allowed for a ~7% increase in Core Size and an ~10% increase in Tank Volume. With a larger 2 row 42mm core, cooling efficiency and capacity are drastically

So since they were listed as down alternative, I was interested to see if they had that artificially puffy feel to them. They do get puffed up really well after a day. And the fabric is cool and comfortable. I do feel like these have good quality stuffing and the cover feels nice. I'm a back sleeper and it's just the right amount of bulk under my neck. I usually bunch the pillow up a little bit there so there's a little more pressure under my neck but with these it just felt good to lay on it without having to bunch it up in any special way. So I would definitely recommend them. So far I'm really liking having these pillows.

Nice and Fluffy

Size: Standard

These "down alternative" pillows have been a winner for me. Came two to a package and once they have a couple of days our of the vacuum packaging are nice and fluffy with no noticable odor. Just the right amount of "spring" to them for my taste. Also don't overheat my face/neck as traditional down pillows sometimes have.

Hotel Grand Set of 2 pillows

Size: King

Excellent quality and comfort. The pillows are soft but with the perfect support, ideal for any sleeping position. They feel fresh thanks to the cotton cover and keep their shape very well. Without a doubt, a great purchase for a hotel-like break at home.

These pillows are super comfortable and feel just like hotel quality. They’re soft but still give great support for my neck and head. I’ve been sleeping much better since I got them. They stay fluffy and don’t go flat, and the material feels nice and cool. Definitely a great purchase
