I have used a Mann oil filter 610/3 on my daughters 1.2 2008 Fiat Grande Punto petrol. Interestingly the EuroCar parts site seems to have a 610/7 filter from Mann. Might be identical apart from capacity. Worth seeing if you can get a local car parts factor to get it for you as they usually seem to get the right part for me everytime.
Micks Garage has W6103...whilst both have M20 x 1.5 as their thread size they are different in height and diameter.
Hope that helps.
