Actually the Spectra are not an oiled filtered. You clean them with soap and water and make sure they are completely drybefore reinstalling it. I am purchasing a spare K&N to use while the other one is drying. This is what I have always done with every filer I have had. It may be a little pricey but it saves a lot of time.
I thought the spectre was an OILED filter. Why would my box include an filled oil spray bottle and a cleaner bottle?
I sprayed my filter before I installed it. If possable I would rather have the dry filter.
