FMDV50 is Forge Motorsports blow off valve solution for the BMW 2.0 turbocharged B48 power units. This valve has been expertly designed and manufactured in the UK, Specifically designed for the BMW 2.0 B48 engine, this is a fully atmospheric (blow off) valve, so you can enjoy that fantastic “pshh” sound! 

This valve is a fully engineered solution offering significantly improved reliability, due to its piston based design with no diaphragm to fail and full aluminium construction.

Furthermore, heavier springs are available and are easy to swap in, to suit your tuning needs if you add more boost pressure to your vehicle.

As with all Forge products FMDV50 is covered by our life time warranty*​​​​​​

Great for keys
Color: Black
I haven’t misplaced my keys since I bought it. I do wish it were a little heavier in weight but it gets the job done

Great for simple jewelry
Color: Black
I’ve had it for some time now, it’s okay. Not the material I was expecting. It’s sturdy. It came with a few scratches, I did get a used one though. I recommend this product for simple jewelry for kids, and get something better quality for your more expensive jewelry.
