  • Blow Off Valve for Hyundai and Honda Civic - Car Enhancements UK

    forge Motorsport Blow Off Valve for Hyundai and Honda Civic

    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.

  • Forge Blow Off Valve and Kit for Audi and VW 1.8 and 2.0 TSI - Car Enhancements UK

    forge Motorsport Forge Blow Off Valve and Kit for Audi and VW 1.8 and 2.0 TSI

    Forge Motorsport is proud to release the latest version of our very popular solenoid driven valve for the 2013-on VAG 1.8 TSI engine (US codes CPKA and CPRA) and 2.0 TSI engine (Euro code CNTA, CHHA, CHHB, CJXB and CJXC;US codes CPLA and CPPA)  including Golf MK7 R. This valve is a full replacement atmospheric blow-off valve (i.e. noisy) that integrates seamlessly with the OEM electronics and results in no detriment in performance, and absolutely NO fault codes or check engine lights, which isn’t something that can be said of our competition! Like our full replacement recirculating valve option, this valve is fully engineered to remedy the failure issues experienced with the OEM solenoid valves when their diaphragm may rupture which results in a boost leak. The later revision OEM valves have a longer lift but ultimately the plastic brittles and in extreme circumstances, parts of the plastic can break off. Our valve uses full billet alloy construction with a piston based internal design that provides for significantly improved reliability over the OEM valves along with lightning fast response. It has also been proven in cars running over 600bhp! This new valve has a very short overall installed height, which enables fitment of this atmospheric valve into the tight space between the turbo and the inlet hose from the airfilter, older larger valves and sandwich plates will not fit this engine.   In The Box:1 x FMDVMK7A Valve1 x Wiring Harness1 x Solenoid, Bracket, and Screws1 x Uprated Blue Spring10 x Cable Ties1 x 1000mm of 4mm Vacuum Tube1 x 5mm T Piece1 x Instructions1 x Forge Keyring and Sticker
