I have to agree. From my perspective, my opinion is the cone K&N didn't do much for me in way of HP before my SC. I tried many different designs... plain exhaust tube running to cone filter in engine compartment, tube running into firewall and connecting to filter, intake running through firewall and into front of VX connecting to filter. Nothing did much, if anything. In fact, half the time it even FELT like it was hindering performance. Sometimes I thought I could feel a difference when the VX was somewhat cold, but after that... nothing.

I ended up just staying with the air box and a drop in filter (AMSOil or K&N. I have both and seem to notice better performance from the K&N, but am aware I am probably dirtying my engine a bit more).
