This is not the only dealer to list this filter size as the correct size for this bike. This is a picture of the crankshaft position sensor on a 2000 FLHTCUI. The black filter here is the 3 3/8" long WIX 57348, not the 3 3/4" long HF171 filter listed here. I have ordered these size 171 filters twice because several websites list them as a direct fit. The angle of this image doesn't allow for interference, but since the HF171 (or any 171 series filter that claims to be ALL site compatible) is too long, you can either install a filter or a sensor. But not both. The filter diameter is outside the sensor head. And I know for a fact that two objects cannot occupy the same space at the same time. If you have an older (1999 or 2000) EFI EFI Electra Glide Ultra Classic, Hiflofiltro HF171C will NOT fit. When ordering a filter for this bike, make sure it is no longer than 3 3/8" (sometimes referred to as 3.4").
