K&N KT-4511XD Replacement Air Filter Product Reviews

Monday, January 1, 2018 - Part KT-4511XD
The filter did not fit my 2012 KTM 250 SX-F (EU) initially. I had to trim some of the moulding away from the inside of my air box to make it sit flush. After a long dusty ride there was no sign that the filter was compromised.
