I was looking under my hood today and decided to take a peek at the cleanliness (or lack there of) of the intake. I changed my oil not too long ago and I looked at the stick and the oil seemed fairly dark for the short amount of time its been in there.

So I took out the rubber (breather hole) that connects from the pipe to the engine. Stuck my pinky in there and it was dirty. You can even see a line of dirt inside the rubber where the air starts. Is the Injen filter of good quality? doesn't seem like its filtering enough dirt.

I know some of you may suggest to get the new dry AEM intake filter but from what I hear, it lets a good amount of dirt though as well. Some people have had complaints about that too....

Anyone suggest a good filter that keeps it clean?

 

i wouldn't say that. see

I've got a long bridge up for sale if your interested. Its quality

 

Yeah, I wish they would compare a regular oem filter in the bunch, they compare all the "bad" filters together.

I just received my fujita cai and took a look at the filter - you can see with light behind it that it is not very fine. These type of filters are designed for minimal filtration and maximum air flow, when compared to an oem type filter.

So I also share your concern, as I plan on keeping my car for a long time and like to keep the engine clean ... without suckin' in extra crap.
