K&N drop-in intakes?!?!?!? plus an exhaust is 300whp? Holy moly. No other mods? Isn't that kindda high. I wonder what gains I have right now by just adding an exhaust, with no other mods. Did I gain like 15whp? (no access to a dyno in my small timbuktu town  )
As far as K&N drop-ins... aside from the worry about fouling the MAF sensor (I am still on the fence regarding this... seen both sides of story), what I am worried about are more the particulates that get in. I mean this from the standpoint that I noticed on my G35, that since I switched to K&N, my oil was a lot darker than pre-K&N. Not sure if there's any truth to that at all... but I also read around that some folks did notice that too. Now what that means.... I would be led to believe that the engine is simply running dirtier... maybe someone else can enlighten me on that topic.

Yes, I am thinking about getting HFC's instead of getting a CAI. So if I have a CBE and HFC's, is a tune needed? I would like to NOT get a tune... don't want to void the warranty just yet. Maybe in a couple of years

Can someone tell me why his post was spam? After reading it, seems like a normal post.... maybe I'm naive
