Product Description
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

Warranty
Warranty Infomation
The majority of Forge Motorsport products come with a limited lifetime warranty (brakes pads excluded). All warranty claims must be accompanied by the original proof of purchase to enable us to help you. Failure to supply this proof will result in your claim or enquiry being denied.
For further information, please call our customer service team on +44(0)1452 380999 or email info@forgemotorsport.co.uk.
Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator, or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.
This warranty does not apply to any defect in the goods arising from fair wear and tear, wilful damage, accident, negligence by you or any third party, use otherwise than as recommended by the supplier, failure to follow the supplier’s instructions, or any alteration or repair carried out without the supplier’s approval.
Please note, all air filters are excluded from the Forge lifetime warranty.
