pipercross crap collector

so having replaced the TB, i was fairly amazed to see the amount of oilly crap in the TB having cleaned it out not long ago.

i know the catch cans will stop lots of fine residue, and there on the list to do.
but i think my pipercross is letting in to many particles of crap. i dont have the original airbox, as mine had the piperx fitted when i bought it, so i guess i need to buy a new box plus what type of filter, is the TRD just a filter or a bit of kit, is it better than K&N

any help as ever

thx

Most use the TRD box and filter - about 50 quid but a bugger to fit :cry:
