The Bilstein B3 air spring provides a perfect driving experience under high load, due to the constant counter-pressure in the bellows of the air spring. This is an optimum OE replacement for vehicles in which the air spring and shock absorber are installed as separate units. Bilstein B3 OE Replacement (Air) suspension air bags are designed to replace the original suspension air bags on select European brand vehicles. Bilstein is an OE supplier for air suspension systems; the quality of these products meets, and typically exceeds, the standards set forth by the vehicle's manufacturer. Each B3 OE Replacement (Air) suspension air bag is designed to connect directly into the original connectors on the vehicle, ensuring modification-free installation and restoration of the original feel of the vehicle.

Features:

  • Uncompromising comfort and driving characteristics
  • Rapid adjustment to road and driving conditions
  • Constant damping power under any load

The delicate axial bellows of the air spring provide very sensitive spring behaviour with a comparably low rolling radius. This ensures optimum functionality even in confined working chambers. Due to the permanent load (contraction, extension, different pressures and temperatures), the material is worn out and may eventually leak. If the air bellows cannot be inflated any more, the vehicle is no longer fit to drive. Technical further developments from the original application to today’s part are usually easily recognizable. Due to higher efficiency and Bilstein's obligation to increasingly employ environmentally friendly materials, the sheathing of the bump stop no longer contains chromium VI. Apart from that, all old parts by Bilstein are recycled in an environmentally friendly manner via the Partslife initiative. Due to the permanent movement and mileage, the high gas-pressure and the permanent oil contact, the seals in particular will become worn. If oil leaks, the air suspension module and other parts such as seals and valves lose their functionality.

Excellent pillow, firm but more flexible than others of its type
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
I previously bought a similar pair of pillows from Sleep Innovations, but they are now either out of stock or unavailable. This new brand is a bit softer and more comfortable than the original pair. It's good for sleeping on my side or my back. The pillow cradles and supports the head and neck in a more contoured way than some harder pillows. The price is reasonable. The only difference from Sleep Innovations is that this pillow does not have a zip cover. So there is no way to wash the exterior. I suppose that one could buy a zip cover for it at extra cost.

Side sleepers rejoice!
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
I have spent hundreds of dollars on pillows. I am primarily a side sleeper and every few years I find myself waking up with a "crick" in my neck accompanied by pain and tension. I have had this pillow for only two nights and I am leaving a positive review. It is firmer than one would expect based on first appearance and the "press" test. The surface stays cool and I can sleep any which way and I am still comfortable. Definitely recommend!

Too Soft for Him, Just Right for Me
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
My husband purchased this for himself but found it to be too soft for his preference. I decided to try it, and it worked well for me. While I agree it’s not as firm as either of us typically like, it still provided adequate support, and the shape retention held up nicely. Overall, it wasn’t a match for him, but it worked just fine for my needs.

Great for a side sleeper. Firm enough that it doesn’t collapse but soft and cool

Love this pillow!
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
I sleep on my side and this pillow is great! I also enjoy the cooling aspect. I forgot my pillow at a hotel and had another one ordered before I got home.
