It uses HKS's proven pull-type sequential valve mechanism with differential pressure control for crisp, reliable relief across the full boost range — from light throttle to high boost — while delivering the signature high-frequency SSQV blow off sound. The kit includes an aluminum charge pipe adapter\/flange that replaces the factory resin component for a direct, factory-like fit. It is offered in a vent-to-atmosphere configuration as well as recirculation (suction return) configurations that route vented air back into the intake to keep the MAF metering intact.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eModel: HKS Super SQV4 \/ SSQV IV (Silver)\u003c\/li\u003e\n\u003cli\u003eType: Pull-type sequential blow off valve with differential pressure (diaphragm) control\u003c\/li\u003e\n\u003cli\u003eOperation: Progressive relief from low to high boost for smooth, consistent response\u003c\/li\u003e\n\u003cli\u003eConstruction: Billet aluminum valve body with aluminum charge-pipe flange (replaces factory resin piece)\u003c\/li\u003e\n\u003cli\u003eSound: High-frequency SSQV blow off tone (atmospheric config)\u003c\/li\u003e\n\u003cli\u003eConfigurations: Vent to atmosphere \/ recirculate to OEM intake \/ recirculate to HKS Carbon Racing Suction intake\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHKS Super SQV4 blow off valve unit\u003c\/li\u003e\n\u003cli\u003eVehicle-specific aluminum flange\/adapter for the intercooler piping\u003c\/li\u003e\n\u003cli\u003eSuction return hose and fittings (recirculation configurations only)\u003c\/li\u003e\n\u003cli\u003eVacuum line, filter, T-fittings, hose clamps, circlip and zip ties\u003c\/li\u003e\n\u003cli\u003eMounting hardware and installation manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRequired extra (Recirculated to HKS Carbon Racing Suction configuration only): the \u003ca href=\"https:\/\/x58cartel.com\/products\/hks-dry-carbon-racing-suction-toyota-gr-supra-a90-a91\"\u003eHKS Carbon Racing Suction intake\u003c\/a\u003e is required and is sold separately — this return-kit configuration routes vented air back into the HKS intake and will not fit the factory airbox.\u003c\/li\u003e\n\u003cli\u003eThe \"Recirculated to OEM intake\" configuration is designed for the factory (stock) airbox — no aftermarket intake required.\u003c\/li\u003e\n\u003cli\u003eThe \"Vented to atmosphere\" configuration exhausts to open air and produces the loudest SSQV sound; recirculation configurations are quieter and keep vented air within the metered intake.\u003c\/li\u003e\n\u003cli\u003eInstallation replaces the factory recirculation\/diverter valve on the charge piping; retain factory routing references and torque fittings per the included HKS manual.\u003c\/li\u003e\n\u003cli\u003eAfter install, verify all hose clamps and the vacuum line connection are secure and leak-free before boosted driving.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePART NUMBER\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e71008-AT021 — Vented to atmosphere\u003c\/li\u003e\n\u003cli\u003e71008-AT021V — Recirculated to OEM intake\u003c\/li\u003e\n\u003cli\u003e71008-AT022V — Recirculated to HKS Carbon Racing Suction intake\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eVEHICLE APPLICATIONS\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eChassis\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eToyota\u003c\/td\u003e\n\u003ctd\u003eGR Supra 3.0\u003c\/td\u003e\n\u003ctd\u003eA90\/A91\u003c\/td\u003e\n\u003ctd\u003eB58\u003c\/td\u003e\n\u003ctd\u003e2020–2026\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"HKS","offers":[{"title":"Vented to Atmosphere","offer_id":53794298495283,"sku":"71008-AT021","price":1320.0,"currency_code":"USD","in_stock":true},{"title":"Recirculated to OEM Intake","offer_id":53794298528051,"sku":"71008-AT021V","price":1430.0,"currency_code":"USD","in_stock":true},{"title":"Recirculated to HKS Carbon Racing Suction Intake","offer_id":53794298560819,"sku":"71008-AT022V","price":1430.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/4226\/2579\/files\/b40c15048cdaf4e18c1ffb5ebb31a2eb.jpg?v=1785886277","url":"https:\/\/x58cartel.com\/products\/hks-super-sqv4-blow-off-valve-kit-toyota-gr-supra-a90-a91","provider":"x58cartel","version":"1.0","type":"link"}
