G35/350Z VQPlug HR 75mm Upgraded Throttle Body Kit | VQ35HR

Unlock the true potential of your VQ35HR-powered G35 or 350Z with the VQPlug Exclusive Dual 75mm Upgraded Throttle Body Kit, designed to replace both OEM throttle bodies with larger, high-flow units. This complete bolt-on kit maximizes intake airflow, improving throttle response, midrange power, and engine breathing—A tune is REQUIRED for this modification. Horsepower gains of 20-30HP have been achieved by upgrading ONLY the throttle bodies on the HR platform.

The biggest performance bottleneck in the VQ35HR platform is its restrictive intake system. By increasing the diameter of both throttle bodies from stock to 75mm, this kit removes a major airflow limitation and sets your engine up for significantly improved performance across the entire powerband. Whether you’re staying naturally aspirated or preparing for boost, this is a foundational upgrade you’ll feel immediately.

Includes everything you need:
• Two Hitachi ETB0021 75mm throttle bodies (high-quality, OEM-grade electronic throttle bodies for smooth and responsive control)
• Two VQPlug-X adapter plates (precisely machined to mount the larger throttle bodies to your OEM HR intake manifold)
• NISformance dual wiring harness adapter (allows plug-and-play connection between the factory harness and the upgraded throttle bodies)
• Two sets of bolts and washers (correctly sized hardware for mounting both throttle bodies and adapter plates)
• Two 75mm throttle body seals (O-ring style gaskets to ensure proper sealing and prevent any vacuum leaks)

Fitment:

• 2007–2008 G35 Sedan VQ35HR

• 2007–2008 350Z VQ35HR

Everything you need is in the box—no surprises, no extra trips to the hardware store—just proven parts designed to perform.
