K&N Cold Air Filter installed on a Porsche 996 C2

Did you notice a big difference in the performance with the K&N? I mean a real seat in the pants push or was it more induction? I'm considering this but I prefer real world opinions.

Thanks

mid range above 4000 rpm rocks

Yes, there is a real difference but it changes the way it delivers power. WIth a stock air box, you get a rush of power from 4000 rpm thru 4700 rpm. After that, the engine flattens out but pulls evenly until about 6000 rpm where it has another surge of pull until 7k.

With the K&N FIPK, I get an even stronger flow of power from 4000 rpm to redline. Flat spots are gone, but power spikes are gone too. Using dynalicious, I get .2 faster 0-60 and quicker 1/4 mile times. I highly recommend it.

If you don't mind the change in the 'character' of the power delivery, it's great.

Plus, the biggest difference, even more so than power is the sound.

Holy moly, when you stab the throttle hard (greater than 70%) you get the loudest, best sounding induction noises that would make even the porsche engineers jealous. You have to really hear it in real life to believe it. It changes the car completely in that respect. I love it.

Just hope it keeps the rain out even with the dry charger.
