Sorry Ive got a derv, so dont know, I put in a BMC panel filter, only because reading some of the post everyone seems to put in different filters.
Suppose if you just bang in a new standard filter, if your one looks a bit black may help.
A lot of guys put a wing mounted air intake system in the 180's, expect someone will be along who knows a lot more than me.
Sure it will be do-able as they are normally very free reving.
