Finally put in the K&N cone filter that I've had for a long time.

I just removed the upper airbox completely and piped the MAFS directly into the cone filter. It was one designed for the Mustang so I figured that it will have similar CFM requirements as our 4.2s I realize the hot air inside the engine bay probably robs some HP, but man the thing takes off now faster than ever! Maybe it was my filthy stock filter or whatever it is, I noticed a significant difference. Also, does the 32v engine have some sort of a valve timing mechanism or dual length intake runners? The harmony of the valves change a pitch around 4k. Man my car sounds aggressive as hell! I just got my 18" RS4s as of an hour ago. I think that I will paint them a graphite color. I will post pictures soon.
