Now that I decided to get the Injen I started to thing about when it rains out.. Once and a while it rains hard and puddles build up here in Jersey..

So my questions is how far down does the air filter go in the bumper. I was told to leave the foam in does this help and work as a shield from water? Does anyone see a future problem with this??

 

I believe there is a valve adapter you can purchase for the intake that allows you to reroute air with a valve from the intake cone in the bumper to a second intake inside the engine compartment. This should keep you safe from hydro lock unless you decide to go river driving. I am waiting for the K&N CAI System as I have scene a more sophistacated version of this secondary valve system on versions of it. Peace.

infidsg35, Like MrElussive has said, it shouldn't be an issue unless the 'puddles' are deep. I just measured the distance from where the Injen filter ends to the ground--- about 12"--- so there's your gauge.(From what I remember of Paintballbitch's Injen). The bottom of the door (if you're stock) is about 12" too so if the water approaches that height, you'd better quit driving and disconnect Mr Injen , (or purchase the diverter valve ReDRoK8 mentioned)
As far as the white foam in the bumper is concerned. I've read that it must be left on so as not to disturb the airflow. This has been linked to the stalling issue at 80 mph. (so I've read).
G/L with your install. I may buy an Injen too if the K&N Typhoon doesn't soon make an appearnce.

Yo Colin wusssssup. I dunno what to tell you mang I'm bent too. I emailed K&N twice already the first time I got a response saying that they are still in the testing phase. I'm assuming they may still be having similiar issues to the First Gen Injen and the Mass air meter or ECU. The second email I sent they never bothered to reply to. Grrrrrrr.... There was a guy I saw posting here a long time ago whom supposedly was on the inside and knew what was going on but I don't remember his username and haven't seen any mention of him in a while? Maybe it's time for another post about the K&N?

I do not know if the Injen CAI is able to use the AEM Bypass valve. This prevents hydrolock in the CAI that dip below the engine and into the lower front bumper area. I know the AEM Bypass valve was retrofitted into CAIs for bimmers, not so sure if it can be used in this particular case.

Just be careful around puddles!

 

Gtorres44, This is the thread from Tech and Mod Forum:
K&N News.

Some time ago I talked with another of us who was involved with their CAI testing---- Socalmmr. I'll have to touch base with him too again and see wassup.
I hope this new Typhoon is really something when it finally does appear. If the time spent in developement is any indication, it will be. Trouble is I'm getting older. LOL [img]/w3timages/icons/smile.gif[/img]

K&N, say there was a guy who was one of the, or the only "test bunny" for the CAI for the coupe. I've got his name somewhere or his handle; I'll look it up. This was back in late May/early June that he was taking his car there. Be back with you if I find it.

The Injen unit routes all the way down to the bottom driver side of the front bumper. The filtter element becomes visable through the bottom mesh grill. I have had one on my G35 coupe for about a month now and have driven through many rain stroms. Regarding water entering the system, in order for this to happen, you would have to sit in a pond of water at least high enough to cover the entire front lower grill of the front bumper, so off the top of my head I would say over a foot and half to two feet. So if you think about it, there shouldn't be aby reason your G should be in anything like that. In everyday rain and snow use, what you really need to worry about is keeping the filtter clean and oiled properly, as its gonna get dirty pretty quick. Access to the filtter gets pretty tight and Injens instructions tell you to remove the WHOLE front bumper cover to install and access it, but I found you can slip it on through the inner front driver side wheel well cover. It takes a little effort but believe me it will work. As for the power, to be honest I dont think I have gained a pennies worth, but the sound it makes is UNREAL! The G sounds like a freakin indy car when you pass through a tunnel. The sound is worth the mod alone, but from what I hear its good for like 5 to 12 ponies, I don't know. I'm not one to look for HP outta of an air filter. I hope this info helps. If you guys want some pics, lett me know and I'll shoot some.

 

I may be misaken but in order for the bypass valves to work (whether it be NISMO, AEM, K&N, etc) the cone head of the intake would have to be submerged completely in water in order for the suction of backpressure to begin at the bypass valve...

sooo... what's to stop a few drops, ounces... from entering the cone up the pipe into the intake when there is no absolte submerssion of the cone?... isn't that enough to damage the engine since water, whether it be a drop or an ounce can't be compressed?

I hope someone can answer this because unless i get a solid answer i'm not putting on my INJEN CAI...

I'm down here in Pensacola FL where it rains all day long...

think of it this way, can you suck water up in a straw if the tip isnt completely under water? no, its physically IMPOSSIBLE, there is no way a little bit of water can get up there.

Well said!

If anyone is that worried about hydro-lcok get the AEM bypass, but take a minute to REALLY think about how it works, and why its designed for MORANS! I hate to be so blunt but its design is so simple and if you ever got any use out of it, that would mean the front of your G would have to be totally immersed UNDER WATER above or mid way your front license plate. All that the AEM bypass is a foam coupling that is attached before the mass air sensor. In the event that the lower air filter is ever immersed in water, it will act as the "bypass" and air will then be drawn through it, instead of being sucked from below. Now, so if that bypass is nothing more than a foam / screen element, is it not in a sense sucking air from the hot engine compartment at the same time the lower one is during normal everyday use? YES IT IS! So it kind of defeats the purpose of having a Cold Air Intake system. Does it make a huge impact of performance, probably not, but hey if you're spending the $$$ to gain the benefits of a CAI, 100% of your $$$ should go for that purpose.

Lastly, "little drops" of water will not hurt anything, as long as its not pouring into the engine. In fact, for those of who are familiar with Water Injection know that in high boost Turbo and Supercharged application a mixture of water and methanol is actually INJECTED into the engine, yes you spray water INTO the intake, and it acts as a cooling agent for the intake. This ultimately enables the engine to reach higher levels of boost safely. So any water droplets that you may suck up through your air filter, would not do any damage, and the bypass wouldnt work in that case anyways....

PS: The oil base of the filter is another key element that retards water from entering it....

***Nismo intake pic -- more pics in link in sig***

Actually, if you have enough vacuum, you can indeed aspirate water through a straw with holes in it. It's not physically impossible, it just makes it more difficult.

The application of that principle however, very likely provides sufficient protection against water injestion under all reasonable circumstances for the G35 in this case.

I understand that prior to the Nismo intake availability and proven compatibility with the G35, lots of people already purchased and installed the Injen CAI. What I can't fathom however, is why people continue to purchase the Injen when the Nismo is virtually identical in design but includes a bypass valve to eliminate the only significant problem reported with the Injen. It costs the same (or less as well); maybe the Nismo doesn't have the penetration yet, since it came out later *shrug*.

Anyway, see the link in my sig for more pictures of the Nismo intake, including the bypass valve.
