Kinetix Velocity Intake & SSV Replacement Hardware Kit – Nissan 350Z / Infiniti G35 VQ35

The Kinetix Velocity Intake & SSV Replacement Hardware Kit contains all the fasteners, plugs, and mounting hardware required for a complete, clean Kinetix Velocity Intake installation on the Nissan 350Z and Infiniti G35 VQ35DE. Whether you’re replacing lost or damaged hardware from a previous install, refreshing an existing Velocity Intake setup, or completing a fresh intake installation, this kit ensures you have every piece of hardware needed to properly mount the intake and address the factory Secondary Swirl Valve (SSV) ports — no sourcing individual fasteners or improvising with hardware store substitutes.

What Is the SSV and Why Does It Matter for the Velocity Intake Install?

The VQ35DE engine uses a Secondary Swirl Valve (SSV) system in the factory intake manifold — a set of butterfly valves designed to improve low-RPM fuel atomisation and emissions compliance. When installing the Kinetix Velocity Intake, the SSV system and its associated vacuum lines, actuators, and ports need to be properly addressed to ensure a clean, leak-free installation without vacuum leaks or check engine codes. This hardware kit provides the correct plugs, caps, and fasteners to properly seal and manage the SSV ports and mounting points during and after the Velocity Intake installation — the right way, with purpose-made hardware rather than improvised solutions.

Key Features

• Complete Hardware Set: All fasteners, plugs, caps, and mounting hardware required for a proper Kinetix Velocity Intake installation — everything in one kit so you’re not sourcing individual pieces separately or making hardware store runs mid-install
• SSV Port Management: Includes the correct hardware to properly address the factory SSV ports and vacuum lines during the Velocity Intake installation — ensuring a clean, leak-free result without vacuum leaks that can cause rough idle, poor throttle response, or check engine codes
• Kinetix-Spec Hardware: Purpose-made hardware matched to the Kinetix Velocity Intake’s specific mounting requirements — correct thread pitch, dimensions, and material spec for the VQ35DE application. Not generic hardware store substitutes
• Replacement & Refresh Use: Ideal for replacing lost or damaged hardware from a previous Velocity Intake install, refreshing an ageing installation, or completing a clean reinstall after engine work
• Kinetix Racing Quality: Kinetix Racing is the specialist manufacturer of the Velocity Intake system for the 350Z/G35 VQ35 platform — this hardware kit is sourced and specified by the same team that designed the intake system itself
