just a quick question...

what's the recommended mileage/time before cleaning the K&N Filter that comes with the Injen CAI.??..

under normal driving conditions...

thanks...

 

I would clean after winter since you get the salt and sand like we do in Ohio. Now I'm in a new development, so dusty environment, so I'll do Post-Winter and Mid-Summer. They say once a year though.

 

How many miles is this cleaning suppose to be done to these filters? I have had mine for about 5k miles already and it is getting kind of dirty.

 

The old school way to determine when to clean/replace an air filter is to shine a shoplight behind the filter. If a good amount of light shines through, it's still serviceable.

 

Yea I had a hydroshield on after winter for about 15k miles, and the hydroshield look shity as hell but the inside was clean just the oil from recharging last at 30k made it all black looking.

 

Air filters actually work a little better when they are slightly dirty because the bit of debris helps collect more debris. But to directly answer the question they say once a year but alot of it is opinion. I clean my K&N drop in ever 15K mi - 25K mi, or once a year really. I don't put a ton of miles on my car though.

 

I guess I will wait till after Winter.

 

k&n recommends that the filter be a little dirty. Clean it whenever you feel the need to. I used to clean mine in a regular basis, but now I just do it when I feel like it needs to be cleaned and i'm in the mood to clean it...lol

 

I just cleaned mine yesterday. I probably do mine every 10-12k, but thats only because I do about 9k a year and its pretty dry and dusty out here...
