This adapter will allow you to mount your 6-bolt MOMO or other 6x70mm pattern steering wheel to the steering column on your Alfa Romeo 159 (939).

MOMO adapter connects the steering column to the MOMO steering wheel. MOMO was among the first to address safety by creating a collapsible hub. Built from a single piece of steel with a spider-like structure fixed to an aluminium base, it is designed to absorb much of the energy generated if the driver’s body strikes the wheel in an accident.

With the intention to guarantee the highest levels of safety, MOMO has carefully selected a programme of models, in combination with collapsible hubs, which have been subjected to the extremely strict TÜV homologation tests. Of fundamental importance among these are the mechanical strength and crash tests. In fact, MOMO is one of the first companies in the world to have passed the tests required for the German homologations TÜV and KBA. Please note that not all vehicles can be TÜV homologated with an aftermarket steering wheel and boss kit. Technology, selected materials and in-depth product knowledge guarantee the consistent production quality of MOMO steering wheels.

Although most cars today feature collapsible steering columns, the additional energy absorption of the MOMO hub provides extra protection. MOMO also offers the industry’s largest catalogue of hubs compatible with hundreds of vehicles. With advanced technology, carefully chosen materials and in-depth product knowledge, MOMO ensures consistent quality and trusted performance.

Please note:
  1. Replacing the steering wheel on cars equipped with airbag systems will disable the airbags for both the driver and the front passenger, as well as any other airbags fitted in the car.
  2. MOMO hub adapters are intended for tuning & racing use only.
  3. Do not attempt to install this kit yourself unless you have been properly trained in the installation and maintenance of car steering wheels.
  4. Do not attempt to install this kit without first reading the instruction manual.
Warning:

Incorrect installation can lead to steering wheel failure, potentially causing an accident that may result in serious personal injury or death.

Nice pillows
Size: Queen, Number of Items: 2
Have had these a few months and so far really like them! They don’t really feel very cooling, but I also run VERY HOT so it could just be me. The foam holds up well and hasn’t flattened like others I’ve tried. They come very compacted- I was shocked how much they expanded!

It works! Quality pillow.
Size: Standard (1 Count), Color: Original White (Cooling)
This does actually provide a cooling effect, and it's very comfortable! The accompanying literature is helpful too. I believe this to be a quality pillow for the price.

Most comfortable pillow I’ve ever slept on
Size: Queen (1 Count), Color: Crescent White(cooling)
This is the most comfortable pillow I have ever slept on. It doesn't mash down like other pillows. Cradles my neck perfectly plus it’s cool. I broke my neck a couple of years ago and this pillow feels very good and comfortable. Definitely recommend to everyone. Ive used it since May and it’s retained its shape.

Smell
Size: Queen (2 Count), Color: Original White (Cooling)
The fact that there are not more comments on the smell of these pillows has me worried about some of yall. Listen, I LOVE the weight, and the firmness, it’s perfect for that. However, these pillows are RANK. They have a very strong mildew-ish smell that lingers. I took the outer cover off and washed it and let the pillow air out for a few days, the smell is still very strong when you press your face against it, which one does because it is in fact designed for that purpose. It smells so bad. It’s nauseating. I can smell it through two pillowcases and blanket that I threw on top of them hoping an extra layer would trap the smell. I’ll bake them in the Texas sun tomorrow and hope that helps, because otherwise these are the perfect pillows for someone who wants to feel like they are hugging a torso but can’t stand the sound/feel of someone else breathing. I don’t know…4 stars, if the smell goes away I’ll come back. Update: many many days later. Either they don’t really smell anymore or I got use to it. They’ve held their firmness and shape well. I like them.
