HKS SSQV IV Kit for GR SUPRA (DB42/DB02) B58

This kit includes the HKS SSQV (Super Sequential Blow-Off) IV valve, designed specifically for the GR Supra models with the DB42/DB02 chassis and B58 engine. The SSQV IV is a popular choice for enthusiasts looking to upgrade their factory blow-off valve system. It's known for its distinctive sound and reliable performance in managing boost pressure.

The Super Sequential design uses a primary valve and a secondary diaphragm, which work together to ensure a quick and complete release of excess turbocharger pressure. This helps prevent compressor surge, a condition that can damage the turbocharger and reduce its lifespan. The SSQV IV features a well-built, die-cast aluminum body and a nickel-plated finish for durability. It also includes a unique, adjustable cap that allows you to fine-tune the blow-off sound, from a subtle whisper to a more pronounced discharge. Installation is designed to be a direct bolt-on replacement for the factory unit, utilizing the original mounting points and vacuum lines, though some minor modifications might be needed depending on specific vehicle configurations.

This kit is a solid option for Supra owners who want to improve their turbocharger's response and protect it from excessive boost. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for the most accurate guidance.
