This is disapointing. I just put a K&N CAI on my truck for nothing?? I have you marketing word.

Interesting article, but two MAJOR things come to mind. First and foremost the test was performed on Diesel powerplants not normally aspirated gas engines. Second the micron size of passed media. Any engine will easily combust "dust" without harm. It's the materials normally larger than 4 to 5 microns that can cause damage depending on the makeup of the media passed. Sand = Bad....leaf dust = nada.
I spent years as a Quality Assurance Manager of a Military motorpool and there as well as other places the old addage of "Figures don't lie, but liars figure" still lives.
Not selling anything, just saying there is a reason why NASCAR, NHRA, IRL and so many others will run nothing other than K&N.

Just my 2 cents.
Yes the test was performed on diesels, and the performance advantage of adding high flow filters for stock normally aspirated gasoline engines is relatively decreased (not as beneficial as applied to FI engines).
The use of high flow filters on race applications is not really a justification for applications to daily drivers. Those race engines undergo complete servicing at a more frequent interval. Lee I am not putting your response in a negative light, it's just that some of the newbs out there may take it out of context.
CAI/high flow filters typically have a low increase in hp (not noticable on stock NA engines), but the throttle response is improved. I installed mine for the sound factor, and it is only used on the street (I change to a high capacity filter when offroading). To make the most of intake upgrades, supporting mods on the exhaust side with a tune is required.

I agree, I can't really feel any real difference with the CIA on the truck. Maybe throttle response is a bit better or it could all be mental because it does sound a lot throatier. People should know that by adding a K&N filter to the stock box or even CAI isn't going to do much for them with out some other major mods. Exhaust, Tune, etc.

I have no heartburn over anything said. I look at this in a strictly professional sense since to me that is what it is. Information can be a great thing as long as it is kept in context and properly applied to the situation. My main concern is that people keep those points in mind when reading reports such as the one mentioned. Like most things in life it's "buyer beware" and I urge anyone to do their research before jumping in and spending big bucks for minimal return on their investment.
As for me personally, I use the K&N flat panel filter in the factory box and am very pleased with it's abilities and functionality.
