We sold our Mini and I have 10 or so (only 7 now remain) brand new Wix 57303 filters still in their original boxes with gasket. $4.00 each picked up in Hillsboro.
Shipping would be additional depending on your location.

These are quality filters at a great price

WIX oil filters in your vehicle's lubrication system play a vital role in protecting your engine from premature wear--every moving part in the engine requires clean oil! WIX oil filters trap more dirt--45 percent more than the leading national brand--which means that they keep filtering long after the competition has completely quit. WIX Filters patented the first spin-on oil filter in 1954 and has been at the forefront of oil filter technology ever since. These oil filters feature strong full-metal base plates to prevent leaks at the double seam under severe driving conditions. They also offer glass-enhanced media that improve the filters' ability to catch and hold engine-damaging dirt. Keep your engines running cleaner for more miles with WIX oil filters.

 

All but one have sold today!
And it wouldn't really be cost effective to buy and ship one filter.
Thanks to those who bought my surplus filters ! Now I need to buy some for my wife's new Miata ;^)
