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

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

kenchan · 02-15-2012, 01:22 PM

op - short answer: NO.

even the amiuzu 350Z doridori test drove (he said fantastic performance) didn't have aftermarket intakes.. only drop-ins.

That's cool! Now I have to add something else to my purchase list...geeze thanks a lot man! hahaha

I installed AEM ETI CAIs with a Stillen CBE. The filters are DRYFLOW and do not need to be oiled. I had a AEM BruteForce intake with dry filters on my Titan and it really performed well. The filters are placed right in front of each tire, behind the fender liner, and if you punch/Dremel out the two small plastic panels on each side your grill, the filters are about 8 in. to each side of the opening. Huge air flow. Since the openings are so close to the filters they also have water repellent covers you can purchase for about 35 bucks each. I purchased these as well and suggest them if anybody were to open up those areas.

AEM provides a DYNO chart on a '09 Z with these intakes that show a 9.67 HP gain.

I had an older 85 z turbo that had the turbo replaced 3 times in 40K miles, according to the original owners reciepts. I drove for about 10k and sold it.
Better to go with CUBIC INCHES or Stroking a motor as compared to turbo etc.

I had a 1983 280zx turbo that never had turbo problems. Ran for 243k, 100k was spent at 8PSI on the stock turbo (Garret TB03) with intake (K&N custom CAI) and exhaust (custom DP-back 3" mandrel bent).

I had a 1988 Toyota Supra Turbo with 212k when I sold her after running 70k on the stock CT-26 turbo at 12-13psi. K&N cone intake, Lexus MAF, 3" mandrel bent DP-back. I never had any turbo problems and the most extensive repairs I ever did on the car was replacing the headgasket on the 7mgte.

I don't believe the reliability or the longevity of the motors of these vehicles were compromised by the K&N filter or modifying the turbos. Both of those cars were overboosted and ran that way for over 50k. If there was a drop in power, it's possible I didn't feel it, but the track numbers didn't change, and they certainly didn't get replaced.

And just for an apples to apples story - my brother had a 1986 300zx turbo - he ran it with K&N/Exaust under ~9psi (T3) for about 5 years before he wrecked it. Yes, the turbo was salvagable.

When you talk about "turbos", which turbos are you talking about and for what engines? How much psi? Nothing you said about turbos reflects my personal experience, nor did I get that impression from the people at zcar.com or supraforums.com who also do turbo builds. Where is all this coming from?

Wait and see what Swift Racing is making for us.

CNC'd velocity stack intakes with custom airbox/resonance chamber... R&D is underway

I talked to my Nissan mechanic about installing cold air intakes and he said it would not make that much difference what do you guys think?

SS_Firehawk · 03-16-2013, 01:39 PM

search the forum, they do make a difference.

KERMIT · 03-16-2013, 05:43 PM

Has anyone measured the real differences? Such as the reduction in pressure drop, decrease in air temperature, increase in mass flow reading, etc? This would be far more valuable than worrying about the end metric which is horsepower.

Everyone jumps to certain conclusions based on company reputation and some dynojet results from a shop in Kentucky.. If the automotive engineers of the world did this... They would be fired on the spot. If the aftermarket cared as much as OEM's about the true metrics behind a product design, we would have much better aftermarket parts.

Yes it has, again documented. When using Cipher, it allows you to monitor IAT's, MAF readings etc. It seems you jumped to conclusions before reading into it.

Did they recalibrate the maf for the new tube?
