SPDZ1 Long Tube Headers - VQ35DE/HR - Nissan 350Z Z33 370z / Infiniti G35 G37

The SPDZ1 Performance Long Tube headers for VQ35DE/HR are designed to replace your factory header. These long tube headers are constructed with 304 brushed 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.

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. 

What’s in the Box:

• 2x Stainless Steel Long Tube Headers
  
• 2x 2 bolt exhaust gaskets 
• 2x Head to manifold gaskets

Because these eliminate the flange between the headers and cats, these fit both VQ35DE as well as VQ35HR & VQ37VHR. Our customers have reported that they fit AWD and RWD, 350Z through Q50, LHD and RHD, as long as they have a VQ
