Drop-in K&N filters - a waste of time/money?

^ Do u think the VVEL on the VHR's do anything to the ECU when adding aftermarket intakes on the car? I mean that could cause a drop in hp from what people are seeing right?

No... CIA will not affect that. The air intake temperature sensor comes after the filters. Meaning, the temperature of the air will not mess with the computer. It would be no different than going from cold weather to hot weather. The AIT senors will adjust accordingly.

K&Ns are a waste of money, IMO. If you're going for track use, you MAY get 1/100th of second better times, but they won't be as consistent. I got more consistent times with paper filters than I did with the K&N. Also, they're REALLY made for off-road use.

Not all oil-based filters are good.
