Diverter Valve Hose for Audi RS3 8Y, RSQ3 F3 and TTRS 8S & Cupra Formentor VZ5

When looking to fit our carbon fibre induction kit FMINDK47 to a 2019 onwards VAG group vehicle that is powered by a DNWA 2019 onwards, you may find that the diverter valve hose to the DV elbow requires an adaptor. Earlier models utilise a straight silicone hose joiner, however these later models use a rectangular joiner. FMBH8 is designed to fit USDM and ROW vehicles that typically use this type of diverter valve hose, whereas European and UK spec vehicles tend to use a straight silicone hose. To identify which you need, please use the reference image below to help identify what variant you have. 

If you have the same as the image on the left, you will require FMBH8 to enable fitting of the Forge Motorsport Intake FMINDK47

FMBH8 uses a 6082 billet Aluminium joiner fully CNC machined by our engineers at our Gloucester HQ in the UK which is then anodised for surface protection. Also supplied is our 4 ply silicone hose that not only improves the aesthetics of your engine bay, but is also of a higher quality than the OEM plastic hose.  As you can always expect from Forge Motorsport products, it’s a high quality fit and forget product.

The Integrated water/methanol port or boost take off port is supplied with a blanking plug help to give further options for your build as you look to modify it further – much like the future proofing we included in the turbo inlet adaptors on our RS3 induction kit FMINDK47.

Although this product has been designed specifically for the Forge Motorsport carbon fibre induction kit FMINDK47 it can be used to run in conjunction with other aftermarket induction kits.

• All fitting hardware supplied (blanking plug thread size is 1/8th NPT)
• The hoses are suitable to be used with either modern long-life coolants, Organic Acid Technology coolants (O.A.T.) or air containing oil mist.
• The construction of the hoses has been engineered to exceed that of the OEM fitments and will enhance any engine bay both technically and aesthetically.
• Stainless steel fasteners
