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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe 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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eAs 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 drivability of the vehicle. Additionally, the valve being open at an idle or vacuum condition is a normal occurrence, 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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eIn The Box:\u003cbr data-mce-fragment=\"1\"\u003e1 x FMDVHGA Valve\u003cbr data-mce-fragment=\"1\"\u003e1 x Uprated Yellow Spring\u003cbr data-mce-fragment=\"1\"\u003e1 x Uprated Blue Spring\u003cbr data-mce-fragment=\"1\"\u003e3 x M6 x 16 Socket Cap Bolts\u003cbr data-mce-fragment=\"1\"\u003e3 x M6 Plain Washers\u003cbr data-mce-fragment=\"1\"\u003e3 x M6 Spring Washers\u003cbr data-mce-fragment=\"1\"\u003e1 x Forge Sticker\u003c\/strong\u003e\u003c\/p\u003e","brand":"Forge Motorsport","offers":[{"title":"Default Title","offer_id":46485919695004,"sku":"FMDVHGA","price":294.2,"currency_code":"CAD","in_stock":true}],"url":"https:\/\/www.mypartsguy.ca\/products\/forge-motorsport-blow-off-valve-for-hyundai-and-honda-civic-fmdvhga","provider":"My Parts Guy MPG Auto","version":"1.0","type":"link"}
