Two key reasons:Hold on, it gets better. The Respons isn’t just a noise-maker. It also;Offers better throttle responseFaster boost recovery on gearshiftUnlimited boost-holding!For example, using GFB’s TMS (Turbo Management System) principle, tests show that the Respons can return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears (more information below)How GFB’s Patented Venting Bias Adjustment WorksTwisting the adjusting ring opens up the atmo port, whilst the recirc port is simultaneously closed.This results in possible venting ratios ranging from 100% recirc, right through to 100% atmosphere and anywhere in between.Fitments:VW Passat B5-B5.5 1.8t 96-05 When Installing A GFB Valve, It Must Be Installed In The OPPOSITE Orientation To The Factory Plastic Bosch Valve - I.E.

However, the VTA vents to atmosphere for sound whilst the DV+ recirculates the air to keep it quiet.Why choose a VTA over a “BOV spacer”?“BOV spacers” are cheap and they make sound. But that’s it. All the inherent performance and reliability issues you get with the factory diverter valve remain, because a spacer doesn’t change the diverter valve in any way. The VTA improves the operation of the diverter valve for sound AND performance.Why choose a VTA over a kit that includes a solenoid?Because there’s no performance benefit to replacing the factory solenoid, only a much higher price! If a VTA with the factory solenoid can open in a couple of hundredths of a second, why pay more than you need to?Fitments:FORD AUSTRALIA Focus RS 2.3L EcoBoost (Mk3 2016-18)FORD Focus RS (LZ, 2016-On)","brand":"GFB Go Fast Bits","offers":[{"title":"Default Title","offer_id":48736224444734,"sku":"GFVM_T9460","price":190.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0051\/2249\/0456\/products\/25tqC8bLIJ.jpg?v=1707509400"},{"product_id":"go-fast-bits-nissan-skyline-gts-t-r33-34-deceptor-pro-ii-remote-adjustable-blow-off-valve","title":"Go Fast Bits Nissan Skyline GTS-T R33-34 Deceptor Pro II Remote Adjustable Blow-Off Valve","description":"Now you can control the sound of the BOV from inside the cabin!Fitments:MAZDA 6 MPS GG MZR L3-VDT 05-OnMAZDA 3 MPS BK MZR L3-VDT 06-09 Direct FitmentNISSAN Skyline R32 GTS-T RB20DET 89-93NISSAN Skyline R33 GTS-T RB25DET 1993-1998MITSUBISHI Galant VR4 E38A-E39A 4G63 90-93MAZDA 3 MPS BL MZR L3-VDT 09-13 Direct FitmentMAZDA CX7 All 2.3 MZR L3-VDT 06-OnNISSAN Skyline R31 GTS-Turbo RB20DET 85-90NISSAN Skyline R34 GT-T RB25DET 98-06MITSUBISHI Eclipse 1G 4G63t 1990-1994","brand":"GFB Go Fast Bits","offers":[{"title":"Default Title","offer_id":48736224903486,"sku":"GFVM_T9502","price":441.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0051\/2249\/0456\/products\/tSlmjJiHx0.jpg?v=1707509413"},{"product_id":"go-fast-bits-ford-focus-st-fully-adjustable-dvx-dual-venting-blow-off-valve","title":"Go Fast Bits Ford Focus ST Fully Adjustable DVX Dual Venting Blow-Off Valve","description":"Fitments:LAND ROVER Evoque 2.0T 2011-2015 (Petrol Only)VOLVO S40 T5 2.5L Turbo 2004-2012VOLVO V50 T5 2.5L Turbo 2004-2010VOLVO C30 T5 2.5L Turbo 2006-2012VOLVO S40 T5 2.5L Turbo 2004-2012VOLVO C70 T5 2.5L Turbo 2006-2012FORD AUSTRALIA Focus XR5\/RS 2.5L Turbo 2006-2012VOLVO S60 \u0026amp; V60 T5 2.0T 2010-2013VOLVO XC60 T5 2.0T 2012-2017LAND ROVER Freelander II 2.0T 2013-2015FORD AUSTRALIA Focus ST 2.0L EcoBoost (Mk3 2012-18)FORD AUSTRALIA Falcon FG Ecoboost 2.0L 2012-2014FORD AUSTRALIA Mondeo 2.0 Ecoboost 2010-OnFORD AUSTRALIA Falcon FGX Ecoboost 2.0L 2014-OnFORD Focus ST\/RS 2.5L Turbo 2006-2012FORD Focus ST 2.0L Ecoboost 2012-On","brand":"GFB Go Fast Bits","offers":[{"title":"Default Title","offer_id":48736225231166,"sku":"gfbT9654","price":233.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0051\/2249\/0456\/products\/itoyt0eEaF.jpg?v=1707509424"},{"product_id":"gfb-dv-performance-diverter-valve","title":"GFB DV+ Performance Diverter Valve","description":"\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003eDV+ Blow Off Valve; Direct Replacement For Factory-Fitted Solenoid-Type Diverter Valve\u003c\/span\u003e\u003c\/p\u003e\n\u003c!----\u003e","brand":"Turn14","offers":[{"title":"Default Title","offer_id":50224320938302,"sku":"gfbT9354","price":159.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0051\/2249\/0456\/files\/92956054-d5c9-4f45-a6d7-fa37900d680d-800.jpg?v=1722623665"}],"url":"https:\/\/carmaspeed.com\/collections\/blow-off-valves-1.oembed","provider":"carmaspeed","version":"1.0","type":"link"}
