Question:

Are they fit on 2008 g35x - Umid

Answer:

Hi Umid, these do not fit AWD

Question:

Will these long tube headers fit on the the vhr motor I have a 2013 rwd g37 sedan - Joban

Answer:

Hi Joban, they have not confirmed fitment on VHR cars. The frame rails are slightly different between HR and VHR so unfortunately we can say for sure that they will fit and clear.

Question:

I have a 2007 hr, will I need the 02 extensions? - Adam

Answer:

Hi Adam, the extensions will not work with the HR, so you would be better off just extending the harnesses on your sensors by way of cutting/splicing in longer wires.

Question:

Will the 02 extender harness work with 2006 revup? Or will this require splicing. - James

Answer:

Hi James, the O2 extension harnesses do not fit the RevUp O2 sensors, you will need to splice for that model.

Question:

Does the extended o2 harness fit vq35hr too? - Jacob Bobbitt

Answer:

Hi Jacob, unfortunately it only fits the DE.

Question:

Would these fit on a 2009 370z? - Paul

Answer:

Hi Paul, these have only been confirmed to fit the DE and HR, but not the VHR.

Question:

Will these fit an 08 hr without modifying them? - David

Answer:

Yes, these fit both DE and HR engines.

Question:

Will these fit on my 2005 350z? Will I need the extended o2 harness? Will the harness be a plug and play type of deal? Thankyou. - Gio

Answer:

Yes, these do fit the 05 350Z. We recommend using ISR's harness to make installation easier, but you can otherwise extend your harness manually if you're not against the wiring involved.

Question:

Will this fit the 2013 g37x - Matt

Answer:

Hey Matt, ISR says it has not yet been tested on any AWD vehicles, but they don't believe it would fit.
