Time to change the oil. Is HD the only filter for these bikes?

 

Nope not the only one, but it is a good choice. 5 micron

 

using the amsoil chrome filters.

 

I like the K&N with the welded nut on the bottom. Makes removal easy. HD one was a chore to remove.

 

I too use the K&N with the nut welded on it. Simple, simple removal and install. I believe the part number is KN-171C

 

I like the WIX. I believe it's 5 micron.

 

Not only the micron rating, but you need to be concerned with the bypass pressure ratings. Here's a list of cross referenced filters for HD

These Oil Filters
have 3/4" x 16tpi threads,
8 psi by-pass valve,
anti-drain back valve.

Available filters include
Purolator PL10241 / PL25230
Mobil1 M1-102
Bosch 3330
AMSOil SMF 133/134/135
Baldwin B1413
Fram PH6022, PH6065A
Hastings LF576
NAPA 1348
Purolator ML16822
WIX 51348

 

No that some of the aftermarkets aren't OK but why not get the one that is made & recommended for your bike ? The GOOD aftermarkets aren't any cheaper !!!

 

I.am thinking...Amsoil chrome or black is a 3 micron {which is finer} + alot cheaper in Canada.

 

Do any of those "after-market filters" listed have a NUT welded to the bottom like the K&N?
