That's K&N

Just curious guys, but is there a difference between the different post-MAF tubes that are out there? I've seen that there are a few different companies that make them, but I wasn't sure if there was any difference.

Takeda afE

Waying out HKS CAI over the Stillen. I know as a community we love the stillen and it is best proven, but when the hood is open the HKS looks more impressive. My question is does any one know the HP trade off from on to the other?

The HKS Intakes will have similar gains to most other short ram intakes for the 370Z. Generally they are between 10-14 whp gains on Short Ram Intakes without a tune.

Thanks for the reply. It's some thing I've been weighing out a lot, especially considering the difference in price.

Are you suggesting that upon dropping in any CAI, a tune is required? Please advise.

[Official] "Which intake should I buy for my Z?" thread.
 

Any intake that doesn't place the filters outside the engine bay is a waste of time and will cost you HP, not gain it. The OEM air box pulls cold air from outside the engine bay. If you go to a short intake with the filter inside the engine bay it will cost you HP. If you aren't going with the Stillen G3 the just buy the Z1 MAF tubes and call it a day.

Required, no, but isn't a bad idea. At a minimum reset the ECU and idle relearn.

I know this topic has been beat to death which is why its a little hard scrolling through 20+ pages to get an answer lol

My question is...what would you guys suggest for building your own CAI? There must be sites that allow this?

I would love to buy the nismo R tune intake but I just can't see spending almost $700 to get very little gain from what u would get just putting together your own...

I do want the CAI to be built with all black parts though any suggestions or links I would appreciate and thanks in advance ����

If you're worried about price, Z1 intakes are the cheapest in town and makes the same power as G3's. They also have all kinds of silicone and some filters too if that's what you fancy.

Well I mean if there's a reason some of these are $500-$700 I'm all for going with them...if they have superior quality to the others then great but if it's just the "NISMO...stillen...injen" name then that's another story :~}

You can get almost the same hp as the long tube intakes with silicone maf hoses and k&n drop in filters and spend $150 or so.

So is there any actual proof that Z1 silicone hoses and k&n drop in filters make as much HP as the long tube CAI? If so, what is the use of going to the more expensive CAI's? Just aesthetics?
Thanks.

There is no proof and that is not possible. Just do some research and you'll find the long tube style make the most power.

Thats not true. Years back someone had a thread showing the gains from a dyno. They were very close to the expensive long tube intakes and keeps more power mid range. That was in combo with the AFE dry flow filters. Many complain about the long tubes having heat soak due to the metal piping...

Also, the description from HPS is showing dyno numbers for the tubes alone:

"Fits Nissan 2009-2013 370Z 3.7L VQ37VHR. Replaces Stock OEM Restrictive Air Intake Hose, improves air flow, reduces heat soak and does NOT trigger check engine light. Delivers dyno-proven performance gains of +6.77 Whp, +6.38 Ft/lbs without any re-tuning. "

The more I read about the silicone intakes and reusable filters (k&n) the more they seem to make sense, especially when you consider the initial cost involved. The fact that they airfilters are easily accessible for cleaning is another huge plus.

As far a gains per dollar the silicone intake pipes and drop in filters is the most cost effective, but they don't come close to getting you 18-20 whp gains. It just depends on what your goals are. Long Tube intakes aren't for everyone.

everyone hear has been talking about performance upgrade, but someone tell me which intake provides the best sound??! that's what i want it for. i already have gthaus exhaust which is JIZZ ~~... help me choose a respectable intake that will help be just as good up high :))

Pair it with the Nismo R-tune Long tube CAI. Has a nice deep growl paired with my FI 18' Res CF CBE. I'd say from hearing some different CAI; G3's Injen, and AAM

The Nismo R-tune CAI have a deeper and louder growl and still gains as much whp as the others as well. Also some other cool specs about the intakes are the water lock filters and no modification being needed to the front crash bar. Most modification is having the holding bracket screwed into a mounting surface to hold them in place.


So win, win.

Intake with the filters in the engine bay will give you a louder sound. Just ask around about the different sounds of the different short ram intakes.

You may pick up a 5 - 8 more up top. The extent to which that is worth it to you is something you'll have to mull over...

Anyway, grab a few beers and skim through this thread for lots and lots of dynos, before and after tuning, various mods, and so forth.

Again, bring beer.

I thought that the Stillen gen III CAI produced 17.5 whp in a 370Z, according to the Stillen web site?

That was the average on a stock Z Sport with 91 octane on a dynojet. We see a range of 15-23 whp depending on the different factors. Fuel, Altitude, Wheel Weight, Additional mods. If you already have an exhaust you don't see as large of a peak gain as they power gains don't add linearly.

Ok that's good to know. So then a Stillen Gen. III CAI will be mod. #2, right after the Stillen CBE.:tup:

Sorry, scratch Stillen CBE and add Fast Intentions CBE instead.

Both are excellent options for exhaust. If you're open to it we would love to earn your business for all your parts needs :)

Thanks Mark. I have already ordered my FI CBE, you guys were a close second though. I think Stillen makes great products but from what I saw and heard, FI had me at "hello". As for the CAI, I am leaning towards Stillen Gen. III.
Cheers.

Just remember, those numbers drop when you add other breathing mods on such as exhaust components...

That is why a lot of people go with the Silicone tubes and drop in filters.

Personally, spending $300+ extra for 5 hp +/- is crazy...

Even when combining the parts the gains are pretty significant. They don't add up linearly but you will still gain more than 10hp from the Gen 3's after doing a good cat-back.

Have any Dyno's to back that up? That would be a really good selling point for you guys. Would be really interesting to see becuase I know a lot of people who stay away from the expensive pipes since most are under the impressions the gains are not very large once adding other mods such as exhaust and the like...

My first mod on the 09 nismo was last week. The new AEM cold air induction kit. Sounds awesome. Definitely feels faster. Woke up the stock nismo exhaust now that it moves air through it. I recommend!

I know that this isn't one of the votable options above, but the Z1 CAI (~$450 currently, but got mine @ $370, Black Friday) is notable.

Gains aside, some merits are that the tubes are partly silicone–so you don't have to cut your radiator support–and the placement of the filters is behind the fascia, right on top of the crash bar–almost impossible to hydrolock your engine.

A similar option is the Takeda CAI, though I have no experience with it's fitment.

I just installed a new Stillen G3 CAI and the Z sounds surprisingly better
with the CAI. Not to mention, I was actually happy surprised on how quicker
my 370Z feels now. Highly recommended.
