Hey all, I have a Injen cold air intake, and it has been raining lately.... I have been doging larger puddles as best I can, but I am tired of having this constant concern over my intake. I was wondering if anyone knows of a water bypass valve that they make for the injen? I can't find it online, I have read about one on a site, but I can't find it on the injen site. Also, can I just use a AEM bypass valve? But where would I put it? And also, I don't want to have to cut my intake piping to put one in. Any help would be great!

i used the aem one and you do need to cut a little piece off the intake pipe to make it fit im actually gunna sell my intake ive had it on for like a month but im gettin out of the mods

 

The only way any water is going to get into your injen is if it gets completely submerged in water and there is nothing else to suck into the engine. If the intake has a choice between air and water, the air will get sucked in becasue it is lighter and smaller (molecules and groups of molecules). Also, the max has a pretty decent splash guard under the left part of the engine (ie the injen filter). I worried about this for a long time also. I mean, if there is running water across an intersection more than 4 inches deep, I will not cross it. Other than that, I dont worry about it. If I think theres a remote possibility of water getting itside, I run the engine up to 4-5k rpm for 10-20 seconds to blow it out. I think it would be way too much trouble to put in a bypass valve, and you may inadvertantly degrade the performance characteristics of the intake.

 

Thats true, I think the actual likely hood that I will suck up water is very unlikely (unless there is a huge down pore and I run into a 4" puddle that I didn't see.) Its just that it has actaully happened to people, and I don't want to have to replace my engine (not that I am close to being able to afford that!) I also have a 1.3" drop, so it makes me even more paranoid. I was just wondering if people had an easy fix for this problem.

Injen also sells a splash guard for the filter cone, I believe... see if you can find that...

 

I think the stock splash guard is sufficient enough. I've had the Injen CAI for almost 2 years. No water. No Problems. The splash guard below it seems to block all the water.

 

This has been debated before. There is no worry about water getting in the engine. If the filter element were completely submerged then the engine would stall. And, if the filter were completely submerged then so would most of the car and you would be floating away with a water damaged car.

 

Just a recap for the worrisome: the Nissan Maxima cannot be used as a U-Boat, with or without a CAI.

 

 

I know someone who hydrolocked his engine because of water entry through a Place Racing CAI. It can and does happen.

 

I hydrolocked my 1990 integra with a stock intake. The stock intake on that car drew air in below the front bumper. I tried to drive through a flooded street where other cars were going. It sucked in water and stalled. Someone in a Jeep pulled me out but the car wouldn't even turn over. Later I pulled the plugs and turned it over. It shot 4 streams of water out of the plug holes. It finally started and with an oil change I was back on the road.

About a year later it ate a bearing due to two bent piston arms and needed a rebuild. Apparently they bent when they tried to compress the water.

I would agree that the intake hole needs to be submerged for it to happen.

 

Good stuff. I think that I will not really do anything about it for now. I know that shiat can happen, but hopefully cali won't flood anytime soon. Thanks all for your input.

Don't drive into a lake and you should be okay.

 

yes i remember that one. but he drove the car through like 3 or more feet of standing water
