Are those of you that already have the Injen Cold Air Intake installed experiencing any type of problems with keeping your filters clean. I am wondering due to the location of the filter itself. Also, do you believe that heavy rain or car washing will affect the filters performance due to the fact that it is in a location where it get wet quite often. Or is the oil in the filter enough to repel the water?

 

I just cleaned mine this past weekend. It's been on for about 2k miles. It was fairly dirty - mostly bugs and road grime. I installed a Grille-Tech front grill which should keep it a bit cleaner.

For those of you that are concerned about water getting into the intake from the rain, etc., I wouldn't worry about it. When I was cleaning the filter element I noticed that water flows through it very, very slowly - even when completely submerged.

 

Yes, the filter does get dirty fairly quickly. However rain is not an issue. I've used an Injen intake on my last two cars and I've run through countless downpours and car washes. The only time you really need to worry about water is deep puddles. If the filter is completely submerged this will induce hydro lock - which is bad as water will be sucked into the engine.

This may be the case when the filter is removed- however if the filter is completely submerged a vacuum will be created and water will be sucked into the engine. Best advise- don't drive through deep puddles.

 

I've never had a problem with mine in rain, carwashes, even small puddles. But I do avoid those bigger puddles like the plague. Just don't want to risk my filter being submerged.

Cleaning it's pretty easy, in fact, I need to go do that soon. It's starting to look a little yucky.

 

is there a way to get the thing clean without taking off the bumper? and how often should it b cleaned?

 

You should not have to remove the bumper just to clean the filter. If you have a Track model though, you will have to remove the difuser and plasting underpanel. I think I will just make it a point to check it every oil change and possibly clean it if needed.

 

All you have to do is remove the diffuser which consists of about 12 screws. The air filter can be reached from the bottom, loosened, and removed. You don't have to remove the arm that it attaches to. Just loosen the filter's clamp. Thats the way I did mine. I ran the car on ramps to facilitate the process. I didn't even remove the bumper to install the hole thing. A lot of elbow grease and the flexible tube slid right through(from the bottom up).

Good Luck!

 

part of the reason you soak the filter with oil is to help repel water that may hit the filter. No worries

 

How much water passing through that filter would mater. Surely some amount of water has to get through it during heavy rain and, if so, would that be enough to cause problems. Do you have to literally submerge the filter to hydro lock.

 

MySunset350Z,

I have not had mine long enough to need a cleaning but am wondering what intervals others have been experiencing.

 

Ive had mine on about 6 months and Ive cleaned it once, but it was mostly big stuff, like leaves, the rest wasnt bad, once every 3 months or so is MORE than enough.

you would have to SUBMERGE the filter to cause any harm to the engine, a bit of water is actually good fro the car.

 

so i guess just about every other oil change ill clean the filter.

 

yup, thats about what I do and so far its working good.
