This valve is suitable for:

Warranty
10 Year Warranty Information
The majority of Forge Motorsport products come with a limited 10 Year 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 +49(0)3222/1097-308 or email info@forgemotorsport.eu.
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.

We cannot quote the appropriate spring from a general mapping level references and you will have to determine the running pressure and then select the appropriate spring from the listing seen below.
Green – up to 10psi (supplied off the shelf with this spring installed).
Yellow – 11psi to 16psi (supplied loose with each valve sale).
Blue - 17psi to 22psi.
Red - 23psi to 27 psi.
Also wot does it actually do, will me car go n drive better .
The FMDVK04D is a serviceable, piston sealed valve; and spring tuning options are also available for this valve to cater for customers who need to hold higher than standard boost pressure.
Otherwise, as a like for like replacement, this piston sealed serviceable valve offers peace of mind reliability and smooth turbo spool; second to none on the market in its class.
