They fit the 2020 model but no website says they fit the 2021 model. I'm hoping its just a update issue.
Be careful, I remember there being a thread on here about K&N oil filters, use the search facility to check what it was.
It is alleged that a nut welded onto the end for use in removal of the filter is poorly engineered and has cracked in use causing oil to leak out. I have one on my 2020 with no problems but will spend the extra couple or dollars at the next oil change for an OEM filter.
Thanks dude. I'm going to assume people put it on too tight and were surprised they cracked it trying to get it off.
I have changed to HiFlo Racing filter. They have thicker canister construction compared to OEM filter, 17mm nut for easy removal and installation. But are quite pricey.
Don’t know what to think about “pricey” or thicker canister construction as being issues to care about. Changing oil every 6 thousand miles makes the $18 ( or less) cost of an OEM Triumph filter an insignificant issue. What?, buy a K&N to save the cost of a beer?
