I just ordered a K&N oil filter # KN-171B. Can someone confirm it'll fit my bike? I didn't see it on their website. Thanks!

 

I know that that is the correct oil filter for the Twin Cams, and am 90% sure it's the correct one for the M8 too.

 

I went off of what would work for a 2017 M8 in a touring model. I couldn't find any information on K&N's website for the 2018's.

 

After wasting a half an hour on the K & N website, I decided to write them using the email address they provided. See below:

tech@knfilters.com

Don't bother; it doesn't work!!! My letter is languishing in my drafts folder. You'll have to call the phone number. Let's see if they've got that right!!

 

According to HD, their oil filter for the 2018 M8's:

"Fits '17-later Milwaukee-Eight®, '99-'17 Twin Cam and '99-later Evolution models (except '08-'13 XR) and can be used as an upgrade for any motorcycle that requires Oil Filter P/N 63796-77A, 63805-80A, 63812-90 or 63813-90."



The KN-171B is what you want.

 

Yay! Thanks. It just came in the mail today.

 

That's what is on my 2018 heritage classic 114. works perfect. Don't waste your time calling K&N. I got some chick on the phone that didn't have a clue. I told her that dealer told me the MOCO didn't change filters from the late model twin cam to the M8 , so the 171-B should work. She told me no it wont work. Some K&N tech ?

 

I didn't think they changed them especially after seeing the 2017 M8s used the same as the TC's. I figured mine would be the same as the 2017s. I would've just went to Harley and bought one but I'd rather have the K&N. I like the nut on the end of the filter plus they have a pretty good rep..

 

K&N alsomake a billet reusable oil filter. Does anyone know if they make one for the M8 as well?

 

If you want a reusable oil filter K & P is what you should be looking at not the reusable K&N.
Do some digging around I'm sure you will be happy with what you see
