Help! I got a Mann oil filter from Evilbay and I am afraid it isn't right. To be honest I have not had the car long enough to know what the proper filter looks like but this thing sure is small. The number on the filter is HU 718/5 and there is also in smaller numbers 100817.

The box says HU 718/5x. It does have the O Ring kit so that's a good sign, are the filters this small? It's not quite the size of a pop can.

Thanks for clearing this up for me.
