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

bucketman · 09-02-2010, 08:43 PM

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

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?
