Autoplicity.com contacted me after my original review and admitted to making a mistake with my order.  They have refunded my shipping and I am happy now.

After 18 days the part finally arrived.  The filter appears to have been sent directly from K&N, but I ordered on the 20th of June, yet the packing date that K&N Engineering Inc. shows is July 3rd.
