HKS Super SQV4 Blow Off Valve
Universal Fitment – Fits Most Turbocharged Models
71008-AK005
Overview:
The HKS Super SQV4 Blow Off Valve is a high-performance, universal fit valve designed to enhance the response and sound of turbocharged engines across a wide range of vehicles. Featuring a unique sequential valve structure and a differential pressure control system, this valve operates smoothly from low to high boost pressures, ensuring stable and reliable performance. Ideal for enthusiasts seeking improved throttle response, distinctive blow-off sound, and enhanced engine bay aesthetics, the Super SQV4 delivers both functional and visual upgrades.
By replacing the factory recirculation valve, which is often inaudible, the Super SQV4 introduces a sharp, high-frequency sound that clearly signals turbo boost release. Its polished aluminum body complements engine compartments, especially when paired with HKS intercooler piping kits, making it a great choice for drivers who value both performance and style.
Key Features:
The HKS Super SQV4 Blow Off Valve incorporates advanced engineering and quality materials to provide precise boost control and an aggressive sound signature. Key features include:
- High-Quality Aluminum Die-Cast Body: Durable and visually appealing, it enhances the look of your engine bay while resisting heat and wear.
- High Stiffness Metal Die-Cast Valve: Ensures reliable and consistent operation under varying boost pressures.
- Triple Fin Design: Triple fins at the center of the funnel create a dynamic and aggressive blow-off sound unique to the Super SQV4.
- Pull-Type Relief Valve Operation: Provides precise relief of excess boost pressure, compatible with a broad range of boost levels.
- Primary Valve (Small): Opens instantly when the throttle is lifted, quickly releasing initial excess boost pressure for immediate response.
- Secondary Valve (Large): Works in conjunction with the primary valve to optimize blow-off performance from low to high boost ranges.
- Dual Valve Sequential System: At low boost, only the primary valve opens; at higher boost levels, both valves open sequentially for smooth, linear boost relief.
- Buff-Polished Casting Pipe Included: Matches the appearance of HKS intercooler piping kits and adds a premium finish to the engine bay.
Construction & Design:
The Super SQV4 features a robust aluminum die-cast body designed for durability and heat resistance, ensuring long-lasting performance in demanding turbocharged environments. The valve’s dual sequential design uses a pull-type relief mechanism, which provides stable and precise boost pressure control regardless of the boost level. The inclusion of a buff-polished casting pipe not only improves aesthetics but also complements other HKS performance components for a cohesive engine bay appearance.
Performance & Sound
While the Super SQV4 does not provide specific horsepower or torque gains, it significantly enhances throttle response by efficiently managing boost pressure release. The unique triple fin design produces a sharp, high-frequency blow-off sound that is both aggressive and unmistakable, replacing the quiet factory recirculation valve noise.
