The G power is a cheap plug and i'd stay away from it. That being said, I wouldn't use the Bosch plug either. The NGK iridium or double platinum will give you thousands of miles of trouble free driving. Iv'e had too many customers [censored] at me after THEY chose Bosch and then had problems. Make sure that you check the gap carefully. There is a myth going around that you don't need to check the gaps on platinum plugs, not true, you have to do it carefully or you risk damaging the electrodes.

Alright bitogonians time for an update.
Today I finally got around to changing the plugs on the wife's FX35. I went with some Bosch laser iridiums which were about $2 each after 5off5 coupons! Everything went smooth,actually smoother than my Z because theres tons more room towards the back of the engine bay.
Now a couple things. I noticed the rear passenger side plug was a little oily. When I got it out there was a little oil on the boot. Not soaked but moist. I've never noticed any real consumption or smoking of the tail pipes. If I'm not mistaken the tube seals are built into the valve cover gaskets which prevents me from simply replacing them.
Second when I went to start the car it smoked for a solid five minutes. We bought the car used late last year so I wouldn't be surprised if I took out the OEM plugs. The electrode was pretty worn down so I'm thinking the car was used to a weak spark and had to relearn the fuel and air ratio. It did go away after a solid highway drive.
Well what do you guys think? Thoughts?

The spark plug tube seals are indeed, built into the valve cover. You'll have to replace the valve covers at $220/ea in order to solve the leakage problem. The smoke was probably from the residual oil dripping into the cylinder during spark plug removal.

Or get a used one for a lot less

+1 Yep leaking tube seals and oil ran into the cylinder through the open plug hole. The cover must be replaced if it gets worse.

Yeah that sounds more like what caused the smoke. Pearl(FX35) was chiefin it pretty hard, so hard the wife got kinda mad. The wife yelled "My car!" I was like "Don't worry babe that's normal..." haha
Anyways, I guess ill keep an eye on consumption and smoking tail pipes. I figure worse case scenario would be to change the plug because of misfire until I get a new passenger side valve cover.
Thanks for the information everyone.

On Maxima.org, Bosch plugs are well known for developing a miss. Nissan builds there engines around and NGK plug. In cross referencing, details are often lost in translation, such as heat range or tip extension.
Always run NGK, flavor doesn't matter as much. I has been said that copper transfers more energy and is better for performance at the cost of shorter life. If your upper intake needs removed for this service you should run double platinum or iridium for the higher mileage.

I have the same engine and NGK Laser platinums are best for this engine.
