After much searching and much contemplation (along with the hooing and haaing), I have decided to change my list to a degree. Most of all, after researching about CAIs I still don't get the fact that there are people that have successful installations without problems and there are people with problems. I really don't want to turn this topic into a silly debate as I have seen on this forum with no real valid claim and fact there is an increase in power or a decrease in power. BUTT-DYNOs are no exception to the rule as it is a matter of perception and probably a placebo to the effect of having something new in the vehicle thinking it works better. So where we go:
1. GroundingGear 8 Wire Performance System - This is a definate must as it improves the smoothness of the VQ35DE.
2. Motordyne's MREV copper plenum spacer (5/16 or 1/2 ich which one?), is the lower plenum needed or should I get the kit to get the most out of it.
3. OEM Z-Tube with a Stillen HF air box. This seems to be a real good combination from alot of members here and is a safe mod. The Injen CAI, well the verdict is still out on this one, because of concerns of hydrolocking and a lame **** explanation that CAIs cause some sort of loss of power with minimal gains. Short RAMs are not considered due to the air temperature increased by the dissipation of heat from the engine, unless I thermally insulate it and could be a pain to deal with.
I would tend to agree with you that its not worth the money given I am going to give it back to Infiniti. But I think that my time with the vehicle is better spent on the fun factor even if it costs a small percentage out of the pocket.
Any other suggestions?? Comments??

IMHO, don't waste the money on a leased car unless you definitely plan on purchasing it after the lease runs out. Just my .02

I would go with the 5/16 spacer over the 1/2 since it seems that there's minimal difference until the higher RPMs. The 5/16 actually seems to be a bit better everywhere else on the RPM band where most of the driving is done. Also, no problem fitting the engine cover if that's important to you.

Okay, checked out the site and thought it was interesting to find the info considering the link I had before was not the same for Motordyne.
So now, I am running into a dilemma... I was thinking of doing the GroundingGear and the Z-Tube with the Stillen box as a first stage to see where things were as far as performance. The second stage would have been to get the 5/16 copper iso plenum spacer, but now with the MREV+, how much of a benefit will I get above the spacer??
Maybe I should swap the spacer mods with Z-Tube and air box. Any of you guys did a spacer mod and then added thel lower plenum?
