If you do your own oil changes like I do and are sick of paying around $40 for an oil filter I've found a site in the USA where you can get the original filter for much less than we pay from the dealer.
These are the original Mann HU 821 oil filter. Go to this web site
www.germanfilters.com.
I've just purchased a 4 pack for $44.97 USD postage $27.00USD cost me $84.84AU shipped USPS Priority Mail. So I have 2 years supply.
They also have the original fuel filters for a fraction of the price we pay over here.
