Actually I just took apart a brand new impy (made around mid-2003) to fit an LPR and it still has the filter. Annoying, because they're slightly too long to fit the LPR nipple in. I cut them down, other people just take them out altogether.Originally posted by mr15bps
there is indeed a filter in an impy BUT only on mid 2k1 and earlier models, as far as i am aware late 2k1's and 2k2's dont have filters in, i have taken mine out on my spare impy and hasnt made any difference at all and no sign of crap in the internals either and i service it regularly... hope that clarifies summin
