ISR Performance 350z VQ35DE primary o2 sensor Harness Extensions.
This harness extension kit is constructed using OEM Housings, Locks, Wire Seals, and Terminals, as well as MIL Spec M22759/32 Tefzel wire.
When installing long tube headers into your 350z 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!
Does not fit 05+ 6-pin O2 Sensors
Our new Compatibility checking feature is still being updated and revised. If you have questions about vehicle fitment, please contact us.
Do you need these for the revup motor? Because on the post for the long tube headers it shows "vq35de non revup only" when you add the 02 extension harness.
Hey Stephen, you will still need to extend your harnesses for the RevUp, we just don't have an easy plug-and-play extension to do it for you.
Does this product come with 2 o2 sensor extensions ? Just want to make sure if I need to buy 2 quantity for both sides or if with 1 quantity is enough for both headers ?
Yes, a purchase of 1 qty gets you both extension harnesses. They are different for left and right sides so they are always sold in pairs.
