Well the time has come for the nwxt round of modifications....<P>What's the group feeling on replacing the 97 850R airbox with a K&N cone setup for warmer months? Would you really notice better response and power or just make more noise?<P>Now what if I do the above combined with a 3" downpipe? More air in and out = more HP from everything I've been told.<P>So who makes bigger downpipes and who sells the cone setups besides Eastern? I like to shop around...<P><P>
