Chrome won’t get you home but this one will!
Great filter for older Harley! Fits great, threads are nice. So easy to use. Lube up the O rings and just spin it on. Good paint on this filter. Way cheaper than Harley plus fast shipping. Even has a hex for using a socket to get it off when needed. Functions like a filter…

K&N, easy on, easy off. Looks great.
Can't go wrong with K&N. I always use these oil filters because I know the quality is there, from the gasket to the outside finish. This same filter comes in black, but I like the chrome forHarley because it is visible when looking at it. The nut molded on to the end of the filter is my favorite thing about it. No need to fumble around with the old filter wrench in that tight area, just a socket on an extension, and it comes off easy. No mess.

Time will tell.
4 stars because the rubber gasket fell off. I pushed it back into place and installed it. There is zero room on my bike for filter wrenches, so the nut on the filter is a huge plus.
