ISR Performance o2 Harness Extension for Nissan VQ37

ISR Performance VQ37 primary o2 sensor Harness Extensions for 4 wire o2 sensor. These are designed to fit the specific 4 wire connector found in most 2011+ 370Z / G37s. 

Sold as a pair. 

NOTE: Please inspect the photos on the listing and compare them to your existing plug type to confirm fitment before ordering.

When installing long tube headers into your 370z or G37 you will need to extend the primary o2 sensor wires, with this kit you will no longer have to cut/splice your o2 sensor wires, this is a direct plug and play!
