RE: K&N bad for our cars
I hve to agree with Jestnomen on this one. The Mann is the way to go for peace of mind - the difference in flow is so little that I don't think you would ever notice the difference in performance. On the other hand, if you want an entirely different intake (CAI or ram-air), then we could debate these issues with more substantive data.
