aFe 3-1 Twisted Steel Headers for 350Z, 370Z, G35, G37, & Q60

The aFe 3-1 twisted steel headers have seen gains of 9hp and 11tq on a stock 350Z, which these were designed for.  Everything about this design was optimized for maximum results from length to collects to shape, etc.  These can be used on the 07+ 350Z, 370Z, and G37 with the following:

VQ35HR AND VQ37VHR MUST USE VQ35DE TEST PIPES or HFCs

These are specifically made for the VQ35DE Engine (03-06 350Z), but they will bolt-up to the VQ35HR and VQ37VHR Engines(07+ 350z, 370Z, G37). The only difference is the flange style at between the header and test pipe. You must use VQ35DE Test Pipes or HFC’s for it to bolt up properly.
