Cold Air Intake for VQ35HR

[belstaff]

Which company does better intake?What brand gives the maximum increment in power?Thanx

[Retired Chief]

There's so many to choose from and so many reviews that you'll get a different answer just about every time. With that being said, I've read really good things about the Injen CAI.

[belstaff]

Thank you! I am also inclined to the INJEN. But what to choose ?!?!!? Short one:



or

Long one:

Typically, and depending on the set-up, the short one is called a pop charger and not a CAI. If you're considering a pop charger then take a look at JWT. Which to choose? That depends on you, what you're looking for in performance and sound, and your driving style. One of the problems associated with a CAI is it can suck water from the ground and into your motor. It's hard to do but it can happen if you drive through a puddle more than a few inches deep or in very heavy rain. There's something you can buy (forget what it's called) that you can install that will reduce the chances of this happening but it also reduces airflow. If you don't drive in the rain then you have nothing to worry about.

It is very cognitive! Perhaps you're right...It's very muddy roads, where I live. And CAI just will bring a lot of problems ... except for suction of water, I will have to wash filters more often. And twist off bumper each time would be very inconvenient.

Probably pop charger - it's my choice



As for JWT... of all pop chargers, it gives the most benefit?More than INJEN or someone else?

i got injen dcia for my 08 (the long one) and its mad nice set up... warning tho u gotta take the front bumper off to put it on... def worth it tho prolly best cia for the z

Take a look at the new Stillen Gen 3 long tube intake that places the filters in front of the radiator. Stillen claims good HP increase. Just came out with version for 350HR motor.

[BusyBadger]

^^^ Beat me to it.

Check out the Stillen website. They've spelled out the recipe for some fairly impressive gains with a few bolt-ons and a little bit of money.

[SemperFiV12]

Injen only has dual CAI (long).JWT, AEM, NISMO, FUJITSUBO have SRI (short ram intakes)Also stillen has longtube. Both me and my friend lost power with injens, and he sold his and got stillens and gained big. My Injens came after my pop chargers, dyno numbers said JWT increased early power band, but could not maintain.

Overall the injens were not worth it. JWT sounded like monsters and really made the car have an amazing inital roar and nasty bite (regret selling it). nd from what my friend says the stillens are worlds better than injens.

All intakes loose power with the exception of stillen. Injens have mixed reviews.

[belstaff]

Thank you very much guys! You helped me a lot!

As I understand it, this kit gives the maximum increment: http://www.stillen.com/product...=350Z #Generation 3, right?

And what about the others two:

#Generation 1 http://www.stillen.com/product...=350Z

AND

#Generation 2 http://www.stillen.com/product...=350Z

Everything I've read is that only the Injen Cold Air Intake will produce more power (albeit a small increase). Everything else will give you a better sound and that's about all. Some intakes will actually decrease power on the HR. Don't trust the manufactures claims, find a dyno graph.

I did a lot of research and found a site with dynos. I'll see if I can find it again. After looking at it I decided to stay stock. It saved me money and some HP.

Just looked at the Stillen 3rd gen intake. It looks promising but I'm going to find someone that has it before I think about getting it myself.

It is said that the injens are the only intakes that provide an increase, it is almost true. Injens barely give any increase.

JWT loose overall power, however the power curve reacts nicely for early in the band.

Stillen gen 3 longtube intakes gain most hp from what i have witnessed.

These all come from personal experiences and few visits to the dynojet. Depending on what you want out of the intake i recommend the JWT and stillen gen 3 for the HR engine.

You said in your ealier post that both you and your friend lost power with the Injen CAI. Now you're saying that you gained a little power. I'm confused. Which is it?

It's between Stillen G3 vs Injen CAI. I'm leaning toward G3, but the price keeps me away from buying it. MSRP $550

Its hard to tell, the tech said the gains werent much as true whp gains but a steadier powerband, and I said I lost power because my numbers with OEM intake were higher, but I have changed exhaust components since then. Either way Injens were a poor investment, and my friends Stillens are not.

[Viggy75]

almost ALL intakes will mess up your maps on the car from the stock air filters... with my injen dcia thats what happened to mine til i had it custom dyno tuned and they fixed all of that

From all the reviews I've read, most CAI's are for looks and sound. The gains on an HR motor are minimal because the stock intake works very well. Technosquare actually recommends the stock intakes when they dyno and re-map ECUs.

So you really gotta ask yourself if the $$ is worth it for the pretty engine bay and for the sound.

I saw something interesting on the injen website about their AMSOIL dry filters. Its oil free and more effective in filtering. And to clean it you can use a shop vac. It looked interesting and may be the reason I end up going for an Injen CAI.

[SemperFiV12]

I wouldnt reccomend Injens... especially for the money. I was way happier with my JWTs.... and my friend really loves his Stillens.

[belstaff]

Thank you All for your opinions. I really need to learn from those who already own a set whether it is worth it.

Weighing the pros and cons I came to think that it is easier to install the compressor. Or supercharger, as you call it.

But it's not so simple... all the sets that I have found, all for the VQ35DE

Have any of you already seen supercharger kits for VQ35HR???

[John@Z1]

G3 is proven to work. Do it you will love it.

F/I kits for the HR are hard to find. You can find a few turbo kits but I haven't seen a single SC kit for the HR. Companies are still making new stuff for the 03-06 models and they already have a ton of stuff for the 370Z but we get very little after market love for our 07-08 350Z's. It's aggravating. We're the red headed step children of the Z community.

[SemperFiV12]

Funny because the HR engines are the best built to withstand internal combustion from FI apps.

It's really not as bad as you would think.

A supercharger for the HR can be priced close to a likes of a TT kit, why do that when there is already a better alternative.

GTM and Stillen are both said to be coming out with supercharger kits for the HR/VHR motors. GTM seems to be further along with a system using the Rotrex blower. A few pictures of the set up have been floating around in the various forums. Stillen is keeping their design secret until it is unveiled.

On other hand, a Twin Turbo kit is available right now from GTM. I've been driving around with it for about 17K miles not with no issues.

Thanks Soup. Do you know who makes the S/C in the first pic? And, for some reason I can't see the second pic.

Hey Guys:

I'm new to the Z world, just bought my first z about 3 weeks ago but I had a chance to meet the guys from Momentum Performance and see their CAI and from what I've seen across all the other CAIs on the market, the MP CAI is the way to go...

350z Cold Air Intake

They had one of their track cars down at the last Z1 event and it sounded awesome with the CAI.

[dasoupdude]

well. a 11 month late response is better than never

If im not mistaken, thats a gtm supercharger kit
