Like I said above, one vehicle with ten filters changed in and out is not a valid nor reliable scientific study by any means.... Further, wasn't that on a diesal engine?

Well, they did use a dyno. Call me nutty, but that carry's a little weight compared to the "it felt faster" point of view.
Yeah, the tests are on a diesel. I've yet to see where K&N builds their filter any different for any application from a Toyota Tercel up to a Viper.
I can't figure out for the life of me why, after reviewing the above website that tests K&N filters, someone would choose to abuse their engine that way unless they figured on selling it instead of keeping it. The test is a damnation of their media, not of the intake system, and beyond that the other test that I referenced is a test of SEVERAL systems. Today's intakes are damned well engineered and don't need, or benefit, from upgrades or modifications with a stock engine. Even at that, I will never believe the K&N claims again unless I see a dyno test, period.
The H3 intake is already a cold air system. Looking at it, and the displacement of the I-5, it's hard to see any gains to be made by spending money on the K&N or any other intake. The stock filter is very large for the engine's displacement. As others have said on here, it's an air pump. If the engine isn't capable of moving more air than the stock filter and intake are capable of flowing without restriction, then there's no benefit to spending the money on the "upgrade".
