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

Speedy

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.

op - short answer: NO.

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

Jordo!

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

search the forum, they do make a difference.

They only make sense for the ppl that already spent the $400 plus, for something that already comes stock on their car.

If you want to change the intake then just get a couple K/N aircleaners.

But your better off to just keep the stock paper filters and replace them at least once a year.

Once an airfilter is dirty you can never get it really as clean as a new one, due to the fact that your dealing with a used dirty air filter that you rinse out in some solvent , blow out with compressed air and then oil it again.

Its like reusing injection needles or your old lady reusing her tampoons.

Its better off to stick with a brand new quality paper filter, cheaper and you know its clean.

CAI's have already been proven superior over drop in filters and post MAF tubes. The stock setup is awesome, but there is a distinct flat spot after 6500 rpm. paper filters are superior when measuring restriction, debatable in cleaning air. Especially R2C intakes.
Exhausts come stock on cars, they generally suck, so we replace them. Likewise the intakes...

Your missing the point, all cars come with air filters and exhaust systems.

Not all cars come stock with factory installed cold air intakes, as the the 370Z does stock.

Post some dyno results of 370z 's that have only had there stock CAI replaced with after market ones, most hp results are very minimal.

Sure if you put some big after market CAI on the car and then put on a good set of headers, large pipes and free flowing muffers and also eliminate the CATS and spend about $2500 and $500 on remapping , you will see some gains, but not from just simply putting on CAI by itself.

Already modded, my car gained at least 10whp from my intakes but I can't give an accurate number because NST pulleys were installed as well. Your still missing the point with the intakes. The stock intakes are still restrictive at the over 6,000rpm, regardless if they are getting cool air away from the engine bay. Tube diameter and new filters account for most of the gains. AEM, Stillen, AAM, Takeda, Akuma, and Injen have CAI's. That's a lot of companies creating a product you think does not work.

Below is a link to AEM's news article on the Nismo 370Z intakes.
2009, 2010 & 2011 Nissan 370Z Nismo 3.7L Get Power with AEM Electronically Tuned Air Intake System

If you don't like them, then dont buy them, don't spread BS that they can only gain hp if you have other breather mods. It's untrue.

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?
