Oxygen Sensor ?'s
 

I am in the process of installing a set of F.I. longtube headers. After removing the factory manifolds I discovered that both oxygen sensors (located in the manifolds, not after cats) were cross threaded into the manifolds. The cheapest price I have found is $318.00 per sensor from Fontana Nissan. Does anyone know where I may be able to pick up a set for a little bit cheaper. Man Nissan is really proud of these things. Oxygen sensors are half as much as the d*%n headers. :shakes head:

Did you manage to get them out? I know that people who had similar issues on other cars where sometimes able to salvage the o2 sensors by reforming the threads with a tap. It might be worth considering if they really cost that much.

they are the same sensors used in the GTR, I had the same issue not a cheap fix, good luck.

Yea I managed to get them out and the threads were shot. No salvaging them at all. One might work but I dont want to chance it. Yea there way over priced.

Damn that sux. My guy at Nissan no longer works there so no helpfrom here. Sorry about not answering my phone I don't get I a signal at work. It is a pain. I will be in Greenville Saturday I'll call to pick up the the cats. If thats cool with ya.

Maybe you could go this route...

I wonder if a shop might have laying around they could let go cheap. Call around. I also wonder if some used ones off a 350 would work.

Here you go bro, The same thing happend to me and I purchased one of these and it works perfect.

That is not the correct sensor, thats a rear sensor.

I guess that's about the best deal you'll find.

Thanks fellows for all the input. I ended up getting them from Daniel at Z1 Motorsports. Those guys always have the best pricing and customer service. According to them this is a very familiar problem. I should have the Z back on the road no later than Monday evening!! :happydance: As far as Nissan and there high dollar O2 sensors they can go f*#k them selves. Oh well we live and learn. Hope this thread helps others from making the same mistake in their future build ups.

I had the same problem but with the one in the cat (technically post cat but in the cat assembly). I replaced it with an NTK for $92 from RockAuto.com, unfortunately though the pre-cat sensor is $167 from them. Looks like Daishi has the best deal on that one. You could always go with a generic one for $30 and change the wires over but I wouldn't trust it, maybe for a post cat sensor it would be ok as it doesn't do much.

Good for you. Glad your on your way back to hitting the streets.

I need to purchase 2 new sensors, which ones do I order? Thanks

you might get lucky with a salvage yard.

hint: G37 uses the same manifolds & O2 sensors.
