ISR Performance HGC Long Tube Headers - VQ35DE/HR - Nissan 350Z Z33 / Infiniti G35

The ISR Performance Long Tube headers for VQ35DE/HR are designed to replace your factory header. These long tube headers are constructed with 304 brushes stainless steel and heavy duty flanges. Designed with a stepped primary, these headers are built to retain as much low and mid range torque as possible while allowing for good top end horsepower gains as well.

The innovative High Ground Clearance, "HGC" design places the collector in a position to maximize ground clearance without sacrificing performance.

Each header features 2 o2 bungs placed downstream of the collector so that you can utilize your factory upstream and downstream o2 sensors. 

You will be required to extend your primary o2 sensor harness to meet the new location which is lower on the header. 

***O2 Extension Harness Fitment: Will only work with 02-04 350z and 03-05 G35 that have the heated O2 sensors with Blue and Green Connectors***
