Product Details
The HKS SUPER SQV (Super Sequential Blow-Off Valve) uses a unique sequential valve structure and a differential pressure control system. This design allows for a well-built blow-off valve that can handle higher boost pressures than stock, while still providing a quick response. The primary valve opens in response to boost pressure, and a secondary valve then opens at a much lower pressure, creating a simultaneous release of excess boost pressure. This dual-stage action helps prevent compressor surge and can improve turbocharger longevity.
Crafted from aluminum and other durable materials, the SUPER SQV 4 is built to withstand the demands of a performance-tuned engine. Its striking visual appeal, often featuring a polished aluminum finish, complements the engine bay. The kit includes all the necessary components for installation, designed to be a direct replacement for the factory blow-off valve or bypass valve system on specific Mitsubishi Lancer Evolution models. This updated version offers improved performance and reliability for enthusiasts looking to fine-tune their forced induction system.
