03 Z for ME

So,

I have the INJEN CAI on my Z. today it just POURED and POURED and wouldn't stop raining....

I drove my Z to work and was worried the entire time as today was the first day I took the car out in the rain after installing the INJEN.

I had no problems at all and the commute was 85 miles....


Has anyone asked INJEN directly about the potential to suck up water with the CAI? I'm curious to see what they'd say.

What are the chances that water is really going to get sucked all the way up that long tube and into the intake? I wonder if might even evaporate in the tube if any SMALL amount made it through, as the intake and engine temperature are pretty darn hot!

It is unlikely that any water is going to get sucked up unless you are in a big enough puddle for the intake to get a whole mouthful.

SO the injen good in the rain?

syf0n

that's what the whole thread is about, I think. Instead of asking someone to sum it up for you, why don't you just read it yourself?

BTW, the bypass valve only works if the entire filter is submerged in water. Or atleast most of it. If a little water gets in there and you suck it up the valve wont react and it will seize your engine if it is enough water.

There has to be a certain amount of pressure build up in order for it to work. The Valve is worthless!!!

just let off the gass until you clear the puddle and accelerate slowly as to not suck up any water!

Yeah, that's another tip -- when I see any sort of large puddle I make sure I am in very high gear or coasting in neutral so that the throttle body isn't wide open and recieving whatever might be in the air stream.

It's not actually a "valve". It's just a highly resistant foam material that won't pass air when the filter is flowing freely, but which will pass air through when the filter is blocked.

My bad sorry I miss read somethings forgive me on that and what I meant was has anyone had any major problems with the Injen?

There will always be a risk of water ingestion with a cold air intake. The
risk is minimal but no matter the risk is still there. The best way to
reduce the chances of hydrolock will be to avoid deep standing water.
Should the filter ever become submerged the chances of hydrolock will
increase. Rain will not affect the intake nor will small puddles. Only if
the filter gets under water.

A day later I get THIS from INJEN. (Take note one reply was from TECH the other was from INFO. I wish they'd both have the SAME answer...

Injen Technology Cold Air Intake Systems should be removed in any wet climates or on any wet roads or highways. Failure to comply with the above warnings may cause water to be absorbed into the engine through the filter causing serious damage to your motor. Injen Technology Co., LTD assumes no liability for damages to your motor due to water entering your engine through the Injen intake system. Although a bypass valve may be used on most systems, it will void warranty and the CARB EO# at this time. Remember, drive safe and drive smart.

Man that got to make you think. Now I am not sure if I should get mines or not.

Well Stillen is now researching to find out if these after market intakes are doing anything at all. My aluminum AEM intake is actually heating the ari before entering the engine and may be causing pinging in my car. Stillen uses the stock air box and said they saw very insignificant gains in the AEM or Injent intakes and a supercharger. So I might be putting my stock box on and throwing my AEM through AEM's office window.

I would just be very very careful whenever there's a puddle. Better safe than sorry cuz I sure wouldn't like the result of it after. I know couple of friends that gotten water in their intakes cuz of puddles, not very good. You don't want to not have your car for awhile.
