My UOAs always look fine and my intake track behind the filter is always clean to the touch so clearly, while not filtering as well as a paper filter (duh) it does well enough for me. Also, I dig the 0-60 runs - the K&N works, it's not BS and for those of us tuning/trying to extract as much as we can out of our cars, it matters.
On a N/A engine, the K&N can help with that 0.1 psi reduction in pressure drop. But on a turbocharged application like a tuned Ford EcoBoost, that 0.1 psi delta in pressure drop is negligible.
