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 sysyems. 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 using cylindrical springs with adjustable pre-load often experience restricted piston travel and a reduction in flow volume. This valve has 34mm pipe connections.   In The Box:1 x FMBSPLTR Valve1 x Valve Blanking Cap1 x 500mm of 4mm Vacuum Tube1 x Instructions1 x Forge Sticker   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.     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.

Blow Off Valve for Hyundai Genesis Sonata and Kia Sportage and Optima. The Forge direct replacement blow-off valve is designed to be a more durable and performance oriented valve than the OEM unit. The OEM valve is suitable for stock boost levels for a period of time, however, once boost pressure is raised, and after prolonged use, the stock valve will no longer be adequate. Raising the boost output of the vehicle will have a number of effects on the OEM valve. First and foremost, the additional boost pressure will quickly exceed the capacity of the OEM spring to keep the valve closed under higher boost levels. Since you cannot change the springs in the OEM valve, it cannot be adjusted for higher boost levels. Secondly, the additional heat generated by the increased boost will quickly deteriorate the OEM rubber valve diaphragm, which will also lose strength with repeated oscillations. The Forge valve uses full billet aluminum construction and Viton silicone o-rings that will withstand the highest boost levels and repeated abuse. It is also tunable for varying boost levels with the included spring tuning kit. If there is ever a problem with the valve such as a torn o-ring, replacements are available free of charge, and the valve is fully rebuildable. As the Genesis Coupe 2.0T does not use a MAF (mass air flow) sensor, there is no reason that the residual boost pressure at throttle lift cannot be vented to the atmosphere such as with this valve. The engine management does not meter the air volume entering the engine, so this residual pressure can be discharged without any adverse affects on the performance or driveability of the vehicle. Additionally, the valve being open at an idle or vacuum condition is a normal occurance, and is not indicative of a leaking valve. If the intake manifold is in vacuum, even while cruising at speed, the valve may be open. The OEM valve operates in this same manner, however, it is just not visible/audible because it is recirculating instead of vented to the atmosphere. Using a stiffer spring to keep the valve closed at a vacuum condition may result in too stiff of a spring tension to effectively discharge pressure at a throttle lift condition.   In The Box:1 x FMDVHGA Valve1 x Uprated Yellow Spring1 x Uprated Blue Spring3 x M6 x 16 Socket Cap Bolts3 x M6 Plain Washers3 x M6 Spring Washers1 x Forge Sticker If you wish to tune this product to fit the needs of your engine, please see the spring tuning kit below.   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.
