I would suspect this is a non-issue. You're not really trying to force air into the filters. When you hit the throttle, they *suck* the air in. As long as they're not placed in some wierd low-pressure area, they'll pull in whatever air they need just fine. The important thing is that the air they have available to suck is cold (relatively speaking). They look fine to me from a water perspective as well, assuming you don't do something stupid like ram a garden hose nozzle up under your intake grille and try to kill them.

Thanks for the explanation! also this is indeed an amazing write up! thanks man... if i was working for STILLEN i would continue sending you products to perform independent testing/write ups... this pretty much made my decision to purchase the intakes...

Still, it'd be nice to know for sure rather than suspecting. I mean, they were on the dyno, the bumper was probably sitting a few feet away... would have been nice for them to slip it on and see if there's a difference.

Why so you can retro fit it to your kia sedona??

Do you even have a 370z???

*sigh*....

He's my RL friend.

He also has a sense of humor. You, apparently, do not.

Musashi · 03-28-2009, 09:38 AM

I do, and my post was a joke.. A lot of haters in the forum and an awful lot of people with no Z that like to make comments.

Very true. He's not one, though. And the point is fairly valid, I'd have probably dyno-ed with the bumper on just to close off any loose ends. But, Im sure, RCZ will baseline it again once he goes to do his exhaust.

And why does someone need to have a Z to make a comment about dyno tuning with a bumper on, anyway? heh. Or was that simply saying that people without Z's or much knowledge about cars in general like to come on here and make blanket statements?

Nice Posting and information/pictures for the intakes.

I'm sold. Good stuff

Asheth · 03-28-2009, 02:46 PM

Hmm have a couple questions.

1) After install would be recommended to reset the ECU?

2) Is a tune necessary or beneficial after this mod i.e. will you see even more gains after a tune?

Although I dont know how to reset the ECU right now, I know anytime you much with the intake, it was good to reset LS1's ECU - this Im sure is no different.

Tune will almost always be beneficial. Necessary, no.

I think for the ECU reset on the 370z and Same for G37 there is a Pedal code which is a little harder and you can just disconnect the Negative battery cable overnight. But you lose radio presets.

The pedal code has been in Nissans and Infiniti's I believe since the 98 Maxima. This is what i found through research. But G37 drivers can confirm!

I disconnected my battery after the exhaust install, and did the same thing after the intake install. I just jot down all my settings on a sheet of paper so that I can easily program everything back to the way I want it. Interestingly enough, you lose all your radio presets, but not any of the XM presets. Other stuff that has to be set back includes audio settings, shift light rpm, oh and this is an important one -- when you hook the battery back up, SRM is off.

however, after rethinking about the location of the filter in relation to the front fascia/bumper and chassis/foam, imo it will actually suck air from underneath the car or the air coming off the asphalt that is bouncing off the radiator... i cant find anywhere other paths the cold air can come in at...as such, i am thinking that if it is hot outside/at the track, this CAI will actually not be sucking cold air in... which kind of goes against what josh is saying and gives more reason to get the scoops...

my problem with this is that i dont like the scoops... so i think if stillen is in development of a front fascia body kit for the z... i think they should put in consideration to establishing better in flow coming from the top of the car/bumper... with that, i believe the 15-20hp gains will be easier to foresee... ( OORRRR ... just take out the foam that is blocking the air... but am no mechanic/engineer, which means i am not quite sure what the impact would be to the car)...

... all this thoughts will probably be answered after SEMTEX's dyno results... -Semtex, just in case my thoughts hold water... i think you should bring your shotgun and use it to put holes on your bumper and re-dyno the car...

There are only so many places you can put these. After looking at the other possible options, it is clear that STILLEN put these in the best possible place.
Remember we also have to install an oil cooler in there and there isnt much room anywhere else. We were pretty impressed with fitment actually, the intakes fit perfectly in that spot and dont need any type of supports. If I had to design the intakes again, I wouldn't change a thing. I may add some gold or plain reflexive foil or a thermo-tec sleeve to the pipes because I dont care as much for how they look, but rather how they perform. This is what Im talking about...

Leave the structural components alone while you can.

1) No, just drive a bit and it will adjust real-time

2) Necessary, no. Beneficial, always.

sylenze · 03-29-2009, 01:20 PM

great point RCZ on the topic of placement of the intakes... you and Stillen got that exactly right, there isnt anywhere else to better place them... my question was do we need to do anything else to also help the intake suck in more cold air to get the optimal performance... i am already sold with those intakes.. i just think the bumper restricts the cold air inflow... which might not be even a valid concern after we see semtex's dyno results...

btw since nobody wants me to take out those damn foams...maybe i can drive with out the bumper instead... i think that's the next best alternative besides driving around with shotgun holes on the bumper... jk ...
