2008 G35S Mods advice
I've just acquired a 2008 G35S Sedan and I've been researching ways to bump up the HP and improve the MPG. Here is what I'm thinking and would like to hear your thoughts..
1 - Installing a intake plenum spacer (either a skunk2, blox racing, or a AAM). Are there any mods needed for this to fit?
2- installing the AAM Test exhaust pipes
3 - installing the stillen stage 3 cold air intake
4- having Z1 do a UPREV reflash/tune?
What should I expect from adding these mods?

G35 sedan w/ too much money in mods
The plenum spacer is only for the 1st gen Gs so it's no use to you. Test pipes will free up your exhaust so you should see more power, intakes really don't do much for our cars other than making them sound better unless you're tuned, and you typically don't want to tune your car until you've installed all the breather mods you're going to get: test pipes/HFCs, intake, exhaust, etc.
I have a first gen sedan and with an R2C intake, plenum spacer, Art pipes, Motordyne XYZ, MD VQ exhaust and Osiris from UpRev I gained 35 hp/tq over stock

Yeah, I'm new to the Infiniti and the luxury sport car world. I love this car as it's a blast to drive! Probably what makes me different then most on here is I'm just as interested in bumping up the MPG as I am the HP. So if I'm trying to figure out is what makes the best combo? Heck, the car already has dual intakes but if I need to do the stillen stage 3 CAI to make the tune work the best then I'm game! New intake spacer, whatever! I'm really not wanting the car to be much louder because I drive a lot. I have the discipline to keep my foot out if it and 2-3mpg per year is worth $600-$800 a year in gas. So I'll use it when I need it. What's the best combo to get me there?

People spend well over 2 grand just for the meager gains of IN/EX upgrades & Tune.

If you drop some K&N filters in the stock air intakes might help yield a better MPG. Changing the plugs might also help MPG depending how old they are.
Most "Mods" don't improve HP on our G's. It's mostly for looks or sound unless you want to drop serious money as Vqsmile stated.
Expect about 10-15hp gain with both Stillen CAI and Uprev tune from what I've read on the forums.
Anyway, hope this helps.
