helo bro
oh they deliver it on sunday?
anyway nice deal wif u 

ya bro,
as u can see on the plastic seal
it stated "factory pre-oiled"

becoz all K&N filter must work wif oil on the filter to catch the dust
oil on the border is normal as well as it work as sealant btw the filter and ur filter box to avoid air go in from there instead of go thru the filter.
if ur K&N filter looks completely dry already then u'll need to wash and reoil it already
