Quick question about Injen CAI
First off, Injen CAI does NOT use K&N filters. they did use their own oiled filters when they first came out but all Injen filters including the SRI now use the Amsoil dry filters which obviously do not need oiling.
Second, The Stillen Gen 3 intake DOES use K&N filters which obviously are oiled.
Third, oiled filters do not mess up anything as long as you follow the instructions and not go overboard with the oiling. I mean seriously if you can install a CAI I'm pretty sure you can follow some cleaning instructions.

? not at all, I never have been employed by any auto company...but I've used a lot of different filters and I take the time to research and find out what works and what doesn't, with any product that goes on my car.
Like I said...if you have evidence of the K&N filters not filtering as well as something else, please share it. If you have evidence that ANY oiled filters can cause damage, please share it.
I guarantee you said evidence doesn't exist. As long as you are oiling the filters to the specified saturation with the correct oil, there is no way you can damage your car. Like I said before, even the OEM paper filters are oiled.
But again, any evidence you have of a product not being as good as people think, please share it. It would be a great help to the community.

Oh no, I've gone and started an internet argument 
Here, this should calm you all down!




On the downside I snapped a bolt holding the left MAF sensor in place but it's holding solid anyway, just going to take it easy until I get it replaced tomorrow.
Don't mind those holes in my bumper, my plugs are in the process of drying.

correct me if i'm wrong but i think the injens are amsoil dry filters...cleaning them is just a matter of using compressed air.
but to access them you need to:
a) take the bumper off...which is 20 min max
or
b) access them from the wheel wells...might need a lift though as you probably would need to remove the bottom plastic cover as well as the wheels.

I'm in for the night and I'm too lazy to go back down to the garage but as I recall, at least on the sport bumper, the middle bottom grille is not false and allows for airflow. I'm pretty sure there's not much between the filters and that bottom area. Also, I'm sure Injen wouldn't design a kit that sits in a place that's going to be cut off, then not tell anyone they need to open up the false vents. Regardless, I'm going to do it anyway (eventually) because in my head it's a good idea.
Edit: Oops, yeah the Injen kit uses Amsoil drys. I was just questioning on behalf of my lazy side. See above for proof of laziness.

It pulls air from in the bumper its not in a hot engine bay and that middle lower grill does brings in AIR .. 20 to clean your filters rarely is not that bad. going back to stock is a other story
enjoy your injens

Like I said, of course doing some personal modification MIGHT add some better airflow, but it isn't a bad design out of the box
Theory: Injen CAI suffocates the filters because the poor filter location. No access to air.
Test: I dynoed my car with Injen CAI with the bumper off so the filters can breathe "fresh" air. Then dynoed it again with the bumper on.
Result: The difference was 1-2hp.
Note: You can open up vents and stuff to expose "fresh" air to the filters but risk the chance of more road debris + water to get to your filter. IMHO, it is not worth that extra 1-2hp.
Another note: I brought up the question about suffocating the filters to Injen's R&D director. What I gathered is that the filters are not suffocated because you can pull air from all around. From the lower + upper grill and the hole on the bottom near the under carriage (check it out). Fact is there's cool air all around and gets pulled when needed. The filter doesn't need to be blasted with open air, which if done incorrectly, can produce a dangerous AF ratio due to leaning. Also, the filters are located furthest away from the injen or any other heat source.
The intuitive but common misconception is that the filters need to be exposed, out in the open for it to get cool air or fresh air. But this is simply not true.

CAI uses non-oiled Amsoil blue filters. I just replaced mine recently by going through the wheel well.
