Is it really worth putting a Cold Air Intake on 370z and what HP gains

Look at the dyno charts, very liitle gain or change in the HP or Torque curves. Real world numbers would be in 1/4 mile times or top speed etc.

You fail to acknowledge that the 370z already comes with a factory tuned cold air intake system.

The other numbers that really count are the ones on a flow bench, connecting the aftermarket CAI system offline to the actual engines heads and measuring the additional air flow, from the intake to the manifold and then to the actual combustion chamber. Comparing the stock to the aftermarket CAI.

That's why I mentioned earlier about drop-ins plus post maf tubes will get close numbers to aftermarket cai becuase the stock system is a cai already. I did look at dyno charts both the manuf. and privately done ones they were similar:
STILLEN 370Z Generation 3 Ultra Long Intake Released! : STILLEN Yes most of the 18 hp gains are up top, but there is a gain still across the board. and if i'm not mistaken, the people running boltons run quicker times than stock per the various discussions on this forum regarding track times.

Cool, what do you have going on in April/May? Mods planned or ?

My car is sleeping until then (chicago). In april I will be putting on the F.I. CBE and maybe CAI.

Nice! I love that FI CBE. I may have to get one myself but I'm having a hard time with the price of a cat back for this car. Over a grand!??

Keep in mind doing the CBE and CAI....you'll gain quite a bit with one or the other...but combined it'll be about the same as one on it's own.

I personally like the idea of drop in filters and the MAF tubes to be cost efficient. I've also had some reservations about those filters hanging out in front of the car getting soaked in the rain.

Yeah the FI exhaust is awesome. one of the reasons it's more expensive then say other japanese cars is you have dual pipes. Also, there are cheaper CBE out there for 650-1000 range. I didn't mind paying more though for the best customer service and high quality products.

CBE alone will be about 20 hp. CAI on top of it will add about 8 more. The reason I said maybe is because my other option is dropins/tubes

I just like the aftermarket CAI because it looks better imo when you pop the hood. I participate in shows and what not around the chicago area.

Dont worry about the filters. all of the aftermarket cai will not get wet unless you drive into a lake. The way they are positioned makes it almost impossible to get them wet from just rain.

Cool, keep me posted on what you decide to do. I agree that FI CBE looks high quality.

I got a Magnaflow stainless steel cat back for my Challenger for $650 shipped and it's dual pipes, canisters, and all that. That's why I had a bit of sticker shock I guess. I still think the FI the best out there from what I've heard though. Even used folks are buying them for $1K which seems weird to me since brand new they're about $1200 - $1400 LOL

If you want to get a nice

... go check prices on the Amuse exhaust and the GT Haus Meisterschaft cbe.

Regardless of the intake setup I'll run before after AFR, timing, intake temp., MAF etc. just to see how it compares. I'll be using the obdII port to data log.

What software or tool will you use?

It's nice these things have wide band AFR available through the OBDII port that saves a bundle of cash having to add that. I had to add a LC-1 wide band to my Challenger and it was like $400 with the gauge and all.

Torque Pro for android with an OBDLink Mx. I tested this on my scion and seems to work fine, the readings for the comparable items (temps, revs, speed) were pretty much spot on so i expect since its pulling data straight from the cpu that it is accurate for AFR, Intake temps, MAF, etc.. The nice feature though is the data logging/graphs and video overlay you can do.

I also have another program for windows (don't remember the name though) that came with the obdLink mx
