Quality Mahle replacement fuel filter for all SPI Minis and early MPI models to VIN 169573. Fuel filters should be replaced every 24k miles or 2 years, whichever comes first.
 
An easy way to check which filter your Mini uses is to note if it uses an adapter on the inlet side. If it does not use an adapter use WC-GFE7057. If it does, use this filter.
