This Blow Off, or Dump valve, is for the Mercedes 2.0 Turbo GDi engine found in the CLA250 that has the electronically controlled bypass valve. It is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade and for unmodified vehicles operating in warmer climates, as a solution to the many failures that have occurred where the original rubber diaphragm splits, which causes a loss of boost pressure. Unfortunately the failure doesn’t always result in a check engine light as the valve can still be blown open by the boost pressure, so you may not be aware that you are losing power due to this.

Our alternative is a fully engineered solution offering significantly improved reliability. Our valve is piston based with no diaphragm to fail, and of all aluminium construction. It replaces the original unit with a pressure/vacuum operated piston valve that still also retains the desirable OEM ECU control over valve actuation.

All parts require for installation are included, together with full installation instructions.

Incredibly Comfortable and Supportive — My New Favorite Pillow！
I wasn’t expecting to love this pillow as much as I do, but the DIORIS large sleeping pillow really exceeded my expectations. From the first night, I noticed a difference in the way my neck and shoulders felt in the morning—less tension, better alignment, and overall more restful sleep. The fill is just the right balance between plush and supportive. It doesn’t flatten out during the night, which is a problem I’ve had with other pillows, especially those that come overstuffed or too soft. This one holds its shape well but still has that cozy, cloud-like feel when you lay your head on it. I’m a side and back sleeper, and this pillow works beautifully in both positions. It’s also large enough that I don’t feel like I’m falling off it during the night, but not so big that it takes over the whole bed. One suggestion: if you’re picky about loft, you might want to give it a gentle fluff or adjust the fill before your first night. But honestly, I didn’t need to do much—it was pretty much perfect out of the bag. Highly recommended if you're looking for a high-quality, comfortable, and generously sized pillow that supports a great night’s sleep!

Hotel like pillow
These pillows were a pleasant surprise. I bought the set for our guest room but ended up keeping them for our own bed after trying them out. They feel incredibly soft yet still provide enough support to keep my neck from feeling stiff in the morning. I sleep on my side and back, and these work great for both positions. My spouse, who usually runs hot at night, said they stayed cool and breathable. The material feels high quality, and I love that they’re machine washable without losing their shape. They fluffed right back up after drying. If you're looking for that plush hotel-pillow feel with everyday practicality, this set really delivers.

Very soft, not firm at all
This pillow is very floppy and not firm at all. It is quite large and I was surprised at the size. My dog has taken a liking to it and decided it's now her new dig bed, which is fine by me, because it's really too soft for my liking. If you like soft pillows then this is for you. If you require something with a bit more support then you won't enjoy this pillow.

Soft and supportive
I recently purchased the this pillow and I am happy with the quality and comfort it provides. Pillow is soft, plush, and supportive without being too firm. The down alternative fill offers the balance of fluffiness and structure, making them ideal for all sleep positions. Whether I’m sleeping on my back, side, or stomach, these pillows adapt beautifully and keep me comfortable throughout the night. They’re also breathable and skin-friendly, which is a huge plus for anyone with sensitive skin. After using them, I wake up feeling well-rested and free of neck stiffness. I like it.

Pillow
These DIORIS pillows are a game-changer! I’ve tried many pillows over the years, but these are by far the best. The down alternative fill is incredibly soft yet supportive, providing just the right amount of fluffiness without feeling too firm or too soft. I sleep on my side, and these pillows cradle my head and neck perfectly, giving me the support I need for a restful night. They’re breathable and skin-friendly, which is great since I tend to get hot while I sleep. The queen size is just right for my bed, and the pillows maintain their shape night after night. They feel like luxury hotel pillows! Highly recommend for anyone looking for a comfortable, supportive, and durable pillow.
