The K and N filter doesnt give a power boost you'd notice BUT the engine did feel crisper somwhow so for the modest outlay i would say well worth getting.
if you also pop a set of iridum spark plugs in as well it would be good as these give a stronger spark and do actally make a noticable, albeit small, improvement to performance throughout the rev range. They last a long time too.
the iridum plugs are available from cain at wolf performance i think.
