I bought three K&N PS-1010 filters on sale at Amazon awhile back for $3.44 each. Went to use one today on my 2020 Acura TLX and it would not thread after several careful attempts. I've been doing DIY oil changes for 57 years and never had this occur before. I installed a Premium Guard PG4612 instead, which went on easily. The starter groove or thread on the K&N filter doesn't look like it was cut right. I believe it was Champion Lab made. I emailed K&N. Waiting to hear back.
