Universal Fitment – Fits Most Turbocharged Models
71008-AK001
Overview:
The HKS Super SQV4 Blow Off Valve is a high-performance, universal fit valve designed to enhance the response and sound of turbocharged vehicles. Featuring a unique sequential valve structure and differential pressure control system, it operates efficiently across a wide boost range—from low to high pressure. This valve is ideal for enthusiasts seeking improved throttle response, a distinctive blow-off sound, and a visually appealing engine bay upgrade.
Unlike factory recirculation valves that are often silent, the Super SQV4 delivers a sharp, high-frequency sound that clearly signals its presence. Its durable construction and polished finish also add a premium look that complements other HKS performance parts, such as their intercooler piping kits.
Key Features:
The HKS Super SQV4 Blow Off Valve combines advanced engineering with quality materials to deliver reliable performance and an aggressive sound signature. Key features include:
- High-Quality Aluminum Die-Cast Body: Provides excellent durability and a polished appearance that enhances the engine compartment.
- High Stiffness Metal Die-Cast Valve: Ensures reliable and consistent operation under varying boost conditions.
- Triple Fin Design: Triple fins positioned at the center of the funnel create a dynamic and aggressive blow-off sound.
- Pull-Type Relief Valve Operation: Offers precise relief of excess boost pressure and supports a broad range of boost levels.
- Primary Valve (Small): Opens instantly when the throttle is lifted to quickly release initial excess boost pressure.
- Secondary Valve (Large): Works in conjunction with the primary valve to optimize blow-off performance from low to high boost.
- Dual Valve Structure with Sequential System: Provides linear and smooth response by activating valves sequentially based on boost pressure.
- Buff-Polished Casting Pipe Included: Matches the aesthetic of HKS intercooler piping kits for a cohesive engine bay look.
Construction & Design:
The Super SQV4 features a robust aluminum die-cast body that balances strength and lightweight design. The valve components are crafted from high-stiffness metal die-cast materials to withstand the rigors of high boost operation. The sequential dual-valve system intelligently manages boost pressure relief, ensuring smooth and stable valve operation across all driving conditions. The buff-polished casting pipe not only enhances durability but also elevates the visual appeal of your engine bay.
Performance & Sound
This blow-off valve significantly improves throttle response by efficiently managing boost pressure during throttle lift-off and reapplication. The unique triple fin design produces a sharp, high-frequency sound that is both aggressive and unmistakable, setting your vehicle apart from those with standard factory valves. The sequential valve operation ensures optimal blow-off performance at all boost levels, enhancing both drivability and auditory feedback.
