not sure what i need...but i want to run some k&n's on my 1100evo....i think theyre generic...but dont know what im looking for and also the adapters to bolt to the throttle bodies....or, do i need a full kit? If i do it looks like the u.s. is the only place i can go...along with a hefty tax bill...so, if i have to buy new anywhere in the uk?....itll be going back on the dyno soon so i thought why not add the filters first...
