ISR Performance HGC Long Tube Headers – Nissan 350Z (Z33), Infiniti G35 & Nissan 370Z (Z34) VQ35DE / VQ35HR

ISR Performance HGC Long Tube Headers are constructed from premium 304 brushed stainless steel with heavy-duty flanges. Engineered with stepped primary tubes, these headers enhance low-to-mid-range torque while also improving top-end horsepower.

The innovative High Ground Clearance (HGC) design strategically positions the collectors to maximize ground clearance without sacrificing performance.

Each header includes two O₂ sensor bungs placed downstream of the collector, allowing you to utilize your factory upstream and downstream O₂ sensors. Note: You will need to extend your primary O₂ sensor harnesses due to the lower sensor placement.
