Overview

The HKS Super SQV4 Blow Off Valve Kit is a unique two-stage sequential blow-off valve system designed for the 2023+ Nissan Z with the VR30DDTT engine. It features a differential pressure control system for a wide operating range and a relief-less operation system that suppresses relief at high boost, maximizing charge response. The kit includes blow-off valves for both banks of the engine, dedicated 4-ply silicone hoses, and a molded return hose.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
