Choosing an oil filter for a Harley-Davidson Dyna or FXR can feel more complicated than it should be. With so many part numbers and cross-reference lists, the real question is whether the HiFlo HF173C covers the bike you actually ride and whether the new-old-stock condition is worth the $14.95 price.
HiFlo Oil Filter HF173C Harley Davidson
The HiFlo Oil Filter HF173C is a spin-on replacement filter aimed at a specific set of Harley-Davidson Dyna and FXR models. It is listed at $14.95 and carries the manufacturer part number HF173C, giving you a concrete reference point to match against your motorcycle's service schedule.
Quick verdict
This filter is best suited to riders who know their exact model code and are comfortable confirming fitment before ordering. It covers a wide slice of the Dyna family and several FXR versions, and the price is within a typical range for a single replacement filter.
Who it suits
The HF173C is specified for the Dyna Convertible FXDS-CONV, Dyna Daytona FXDB, 1992 Dyna Glide Custom FXDC, 1992 Dyna Low Rider FXDL, Dyna Low Rider Convertible FXDS-CONV, 1994 Dyna Sturgis FXDB, 1991 Dyna Super Glide FXD, and Dyna Wide Glide FXDWG. The listing also covers the FXR 2 from 1999, FXR 3 from 1999, and FXR 4 from 2000. If your bike falls into one of those model-and-year groups, this filter is a plausible match.
What stands out from the listed details
The first thing that stands out is the specificity. This isn't a one-size-fits-all filter; it's tied to a particular set of Harley-Davidson models and a specific part number. The seller describes it as new old stock, meaning you're getting an unused filter that has been in inventory rather than a freshly manufactured unit. For some riders, that's fine, especially if you're stocking up for a scheduled oil change. The filter is also marked as manufactured in Thailand, which is worth knowing if country of origin matters to you.
Meaningful trade-offs
The biggest trade-off is the fitment caveat. The seller explicitly says they research parts to find fitment but do not guarantee that all applications are 100% accurate as listed. That makes the model list a strong starting point rather than a final confirmation. If you have a Dyna or FXR variant that's close to but not exactly one of the listed codes, double-check the HF173C against your motorcycle's parts diagram or service manual before committing.
There's also the new old stock condition. While it can be a good way to get a genuine part at a normal price, older inventory may not carry the same shelf-life assurances as a fresh production run. That's not a reason to avoid it, but it's a detail to factor in, especially if you plan to store the filter for a while before use.
Bottom line
The HiFlo Oil Filter HF173C is a reasonable choice for a rider with a Dyna or FXR model explicitly listed in the application notes, and the $14.95 price is straightforward for a single filter. Just treat the fitment list as a guide rather than a guarantee, confirm your exact model code, and you'll be in good shape for your next oil change.
