Thoughts ?? Injen SP Series Dual Cold Air Intake - 09+ Nissan 370z Nismo
 

Hey all, I have been looking into getting these for my Nismo. They say they have had a +13 hp but still have yet to see the dyno.

I was also considering getting the hydroshields for the filters, even though I barely drive the car when there is bad weather, but sometimes get caught up in it.

I was planning on doing a DIY, but wanted to see if anyone else has put these on your Nismo.


Thanks in Advance,

Tim

Hey Tim, Did you ever install the Injen Air Intake? I'm looking to do this for my Nismo but I'm trying to see of there are others that might be better.

Thanks to know.

The hydro shield is pretty useless if you ask me. You will probably lose some power from it.

Anyways, my RSX used to have a CAI and I drove it through storms. Never had a problem. I even had a open fender well when driving. I know it is bad but I never hydrolocked it.

So if you do not plan on driving your car into a river then you do not need a hydro shield. Unless you live in a area that floods a lot and you plan to have your car sit in a flood.

Useless unless you drive in flooded streets often, which probably means you'll have more issues than a flooded motor. It's cheap insurance but not needed 99% of the time, and you'll lose power in the process.

Currently Injen has the only Nismo-specific intake model, but that doesn't mean you're limited to just that intake. Stillen fits with a minor retrimming of the bumper ducting, as does the AEM one. We currently run the AEM intakes on our shop Nismo.

We carry both in stock! :D

I just bought the hydroshields, because a couple weeks ago, my injen intakes caused me to hydrolock my motor in about 5-6 inches of water that I had to go through to exit a parking lot at my job. Cost my insurance around $9,000 and me a $500 deductible, to replace the short block. I'd get them as a pre-caution if your sticking w/ injen, or just like was said above, modify something else. You never know when you'll be trapped and forced to go through a flood, or deep puddle. Air still goes through the shields pretty easily, but not water, so I doubt any power would be lost. Maybe less then 1 hp if that matters. Just got them in today.

im sorry but this whole post just sounds silly. what the heck are you doing driving through 5-6 inches of water. thats a deep spot man! i know what area of texas you live in and you should know by now just to let it sit an hour or two and the deep water will disperse. i wouldnt even want my car back if it had water damage.

How low was the car? A stock Nismo is still nearly 5" off the ground. Going down a ramp the nose could dip into a puddle, but it'd have to be pretty deep.

Have you ever been forced to go through it as soon as you hit it and no place to U-turn because of a median, and a crap load of traffic directly behind you inching forward for you to move the hell out the way. Umm guess not. Imagine every street you turn on is flooded...galleria area. But yea this instance happened while exiting a parking lot while it was pouring rain, once I hit the gated arm there was a deep dip as stated above, and the nose of the car went under, and engine immediately died. You act like you can foresee all circumstances and events. I for one didn't know water was going to be there until I visually saw it. Anyways go ahead and take your chances with Injen, they obviously make the shields for a reason. I suppose they've had this complaint before...hmm

Oh and car was stock height.

Interesting........

Even with the shield you can still hydrolock. No matter what you do, if you drive into a huge puddle that is deep enough, you will hydrolock. The shield only prevents hydrolocking from too much water splashing up into the intake filters.

What you should of done instead was put on your hazards and stop before driving into the huge puddle and detached your intakes from the manifold. It would of at least saved your engine.

I agree...I know that now. But what's done is done, and car is back up and running. I will not make the same mistake again. People behind me will have to wait.

Ive been thinking of buying this as well but have been curious about the installation process. Do you have to remove the bumper or cut anything or can they slide in somehow?

Hey Pelican,

You have to remove the front bumper but it's not hard at all. You also need to use their replacement washer fluid bottle but it's actually pretty easy. Probably 1-2 hrs max IMO.

BTW we carry the Nismo edition Injen CAI if you're interested.

If I were you, I'd rather stop and kill the engine put my hazard lights and call for a tow truck. Better save for a bigger headache and don't mind the people behind you, they can't do anything.

Thanks for the info. That just makes me too nervous to do that, maybe because I still only have about 900 miles on it. Any other suggestions?

I was in the EXACT same situation last week. There was water everywhere but not more than 2-3". Then I made a right turn and bam, I'm forced to drive through 6" of water. I couldn't avoid or make u turn as it's a busy street and cars are waiting behind me. Luckily I don't have Injens :tup:. I drove through water like this :driving:

Well if it makes you feel better, we ordered coilovers before taking delivery of our shop Nismo, and long tube headers and AEM intakes were installed before we hit 500 miles :p

Which part are you nervous about? The bottle replacement or the bumper removal? All of the CAI units on the market will require some type of modification-

AEM- bottle relocation/replacement, metal ducting modification (Nismo model specific for guide modification). Bumper removal during install.
Injen- bottle replacement. Bumper removal during install
Stillen- Metal air guide modification (Nismo model). Bumper removal during install.

So unless you're willing to just invest in K&N/Mines/HKS drop in filter elements or even a short ram intake (which don't produce significant power gains compared to CAI), you're looking at some type of modification.

No, it just makes me nervous because its new and its my baby lol. the main part is takign off the bumper. god forbid i break a clip or mess something up...

There's not very many parts you can break :)

Actually I was in your same situation but it's very easy. However, you need another friend to hold the other side so that it doesn't come down hard on the floor. Other than that, it's very easy. Please follow Digitoniums DIY

I can take it off and put it back in less than 10 minutes! :tup:

What about the Stillen kit for the 370? that doesnt look like it needs the washer fluid resevoir moved...

The Stillen kit will not require the washer bottle to be relocated but you will need to trim your radiator support and the extra Nismo ducting on the bumper support.

IT will hit the bumper just a little bit. The injen and aem has some issues with the stillen bumper. The aem relocates the washer bottle to the middle.

^^ if that's true then my mistake. I happened to talk to Josh from Stillen during a meet and he only mentioned the metal air guide interference when I inquired about Nismo
model fitment.

I was contemplating on that particular intake and some others. I decided to go with the K&N typhoon kit because I never have to worry with this problem and I really didnt want to deal with taking my front bumper off to clean my airfilter's. Im sure it may get you five more hp'r or so but I didnt think it was worth the trouble or extra $$. The injen and K&N are the only ones that have the intake tubing that necks down which made me believe thats where they are picking up the extra power due to velocity. Injen will provide a cooler charge though im sure. Just a thought.

I noticed on Speedelements.com website that the Takeda short ram intake claims a 9 WHP gain. Thats pretty good for a short ram. Does anyone have any experience with this one? I was thinking that the cleaning of air filters on the injen would be a hastle to take the bumper off every time it needs cleaning...

Tim, I was just in my local dealer for service on my Nizmo and I noticed that they have a cold air intake for a regular 370Z. I asked the parts guy if they have one for a Nizmo and he told me that Nissan is working on putting one out for the Nizmo, due out sometime later this year from Nissan. His manager was looking for one for his Nizmo. Check out your local dealer.

hhhmmmm.. sounds like a lot of problems with water, or additional modding needed during install.

Anyone got a real recommendation for a Nismo Intake yet?

This will probably be my next mod, but I'm not looking for more trouble LOL

I installed the Injen on mine about a year ago. We have heavy rain and lots of water down here. So far on problems, very happy with the intakes. Did not know that Injen made a Nismo specific intake, or at least not when I bought. Install was easy. Just have to replace washer bottle. Oh by the way if you install the Injen and replace the water bottle, do your self a favor and throw some paint on the metal bracket for the bottle. Went to clean my filters and the small pieces of sheet metal were rusting. No biggy.

I found these part numbers for the Nismo specific Injen intake.

SP1990P - Chrome
SP1990BLK - Black

Maybe one of the Vendors could confirm these part numbers for us.

So anyone actually recommend this intake?, not sure I want issue with water as mentioned..

Anyone else running the Injen intake on a Nismo yet?

Not running the Injen, but I am running the AEM which is of a similar design since it also draws air from the same area. The power difference was definitely noticeable, especially at mid/high RPM range.

TROOPER (Darren) has the correct part numbers for the corresponding Injen intakes for the Nismo.

What's the difference between Injen CAI for a regular 370 and a Nismo? When I installed mine, Injen only made one type. I had zero problems installing it, just wondering.

Victor, do you stock these for the Nismo?
I'll be looking for the black version (SP1990BLK) at some point.

Yes we do. I have one polished, two in black powdercoat at our East Coast warehouse. Let me know when you're interested and I'll check the stock again :tup:

I spent the past two years with, what looks like the exact same kit, on my 2010 370z NISMO.

The first year (in El Paso) it was fun to have the guttural sound kick in with my foot planting the gas pedal. I had zero issues even though one of the younger guys at the garage told me, as they were being put on, "They're great, but now you won't be able to drive in the rain." Which, at the time, I kind of laughed off.

However, this past year was a nightmare in New Orleans -- all kinds of issues with the sensor(s) tripping. Very stressful during "tropical events" here for me. At times I'd be traveling to work between 5-20 MPH hoping not to kick in the full-use of the intakes much.

A couple of things to keep in mind though: 1) New Orleans comes with pro-level thunderstorms/showers. Rarely will you encounter the typical la-di-da rain you might expect elsewhere. It also has a challenged water system (as every drop that enters the greater New Orleans area has to be pumped out); and 2) I did not use the hydro shields as others have suggested in previous posts.

I just recently moved back to the stock intakes -- just in time to move to the Mojave Desert. The irony of it all!

As a side note, a buddy of mine who also had Injen intakes on his 350z recently had complete hyrdolock and is in the process of having another engine put in it.

It sounds, however, that he misread some water following a downpour -- I.E. it wasn't an inch or two but closer to a foot or more.

I suppose all this means is: 1) Know when and where you'll be driving weather wise; 2) Definitely get the shields -- can't hurt, and 3) New Orleans is NOT the ideal area of our nation to strap on a pair of Injen CAIs, or any other for that matter. That's unless you have a second car and only run your "Z" during good weather.

Just my thoughts. Again, the intakes worked fine in conditions more appropriate for them. AND, I was warned way back in early 2012 that I might not want to drive in the rain. To add more irony to the picture, I sold off my jeep and ONLY took the "Z" to New Orleans/Chalmette. And BTW: New Orleans roads (Magazine St. to name one) are not made for hyper-low sitting autos such as the "Z." The curbs are higher than average and the roads can be unforgiven for both car and driver.

Wow! As they say timing is everything.

I had the Injen kit fitted to my 370z yesterday at the leading Z tuner's in the UK. It gave me an extra 11bhp at the wheel, looks great and sounds awesome, but nobody mentioned the potential issues with rain.

Reading this thread worries me. are you saying that driving rain could be a problem, or just standing water more than 5 or so inches?
