Performance - Audi A4 B6 (2000-2006)

The Splitter is a truly remarkable valve that gives a combination of blow off and recirculation valve operation, all at the same time, and has been specifically designed for the many turbo engined applications that operate metered airflow management systems. This means you get all the noise of the blow off valve whilst retaining the compatibility with the recirculation requirements of the engine management system. As a bonus we also offer the ability to convert the valve to recirculation only mode for those times when stealth running is required. This valve uses a Brass piston which utilises new sealing technology along with a variable spring preload, incorporating a ratchet type top adjuster that will allow for the positive and precise adjustment to match the valve to your engine. This is achieved by using a unique single, conical, progressive rate spring, that can allow for the retention of boost pressure over a wide adjustment range. This unique spring design also allows for unrestricted piston travel and flow volume regardless of the amount of pre-load adjustment added to the spring. Other manufacturers' valves use cylindrical springs with adjustable pre-load, which often experience restricted piston travel and a reduction in flow volume. When we say our products are Engineered For Performance, it's not a catchy sales phrase, it's the truth. and we prove it with every product we manufacture. Note: This valve requires installing the opposite way to the original Bosch Valve. This means that the side pipe is fitted into the Turbo Intake Hose, and the base pipe connects to the hose that runs to the boost side of the turbo.   In The Box:1 x FMDVSPLTR Valve1 x Valve Blanking Cap1 x Instruction Booklet1 x Forge Sticker If you are unsure if this product is suitable for your application, please contact us.  The valve has a port size of 25mm fits: AudiA31.8TA41.8T (B5,B6 Models)A61.8T (B5,B6 Models)S31.8T (8L Chassis)TTMk1150/180BHP210/225BHPSeatIbizaMk2 (6K2) 1999-2002PetrolMk3 (6L) 2002-2008PetrolLeonMk1 1998-2005Cupra 1.8TCupra R 1.8TSkodaOctavia1.8TVolkswagenBeetle1.8TBora (1998-2005)GolfMK41.8TPassat1.8TPolo1.8T         To service this valve, access the valve piston by removing the 3 cap screws at the base of the valve and simply clean the piston chamber using brake cleaner or similar cleaning fluid before installing the new spring and piston. Please observe the correct spring and piston orientation when installing the serviceable parts, as seen in the attached drawing.   Adjustment guide. First turn the valve adjustment knob all the way down in the anti-clockwise direction, which will adjust the spring it to its lowest tension. Then turn the valve adjustment knob in the clockwise direction to the appropriate tension level, as set out below. Standard engine – 16 clicks. Stage 1 remap – 21 clicks. Stage 2 remap – 25 clicks. These adjustment recommendations are a general guide and you may find that your engine requires fine tuning by 1 or 2 clicks in either direction to achieve optimum performance. There will be no significant performance benefit adjusting the valve over 30 clicks as the spring will have reached its maximum operating tension.     Please Note: In line with our policy to constantly review, revise, and improve our product range, the appearance of the product you receive may differ from the one advertised.   Fits Multiple Vehicles

Now you can fine tune your Blow Off/Diverter Valve to the exact needs of your engine with this complete tuning kit. If you are finding that the valve is dumping more than required, or if you are losing boost pressure it is normally an indication that a stronger spring is required. Alternatively, if the valve is failing to dump it may be necessary to install a weaker spring. Please note that fitting a stronger spring into a valve will not increase boost pressure, unless existing pressure is being lost. Failure to allow the valve to operate by installing a spring which is too strong, may cause damage to the turbocharger. Please also note that the red coded springs should not be installed in the DVR or DV007 diaphragm valves.  Valve Spring color coding: Green - 5-15 PSI, Yellow - 15-23 PSI, Blue - 23-30 PSI, Red - 30 + PSI.*The above figures are estimates only and should only be considered as a guideline* Note: Serious or fatal damage may occur to the engine and associated components if this product is incorrectly matched to the individual engine requirements. Forge Motorsport nor any of it’s authorised distributors can assume any responsibility for any adverse effects resulting from the installation of this product.  Please contact us if you are uncertain whether this kit is suitable for your valve. *Please Note - The colours of the springs illustrated may differ to what you receive.
