Spin-on style oil filter to suit 105 series engines from about 1972 onwards. Ideal for all 2000 engines and later 1600 motors - high quailty direct replacement for original sized Alfa oil filters made by the O/E manufacturer for Ferrari (UFI) or FRAM (O/E for Alfa back in the 1960's and 1970's until they started manufacturing their own filters). Also fits Montreal engines. Classic Alfa recommend this filter over the smaller original filter available now from Alfa (EN046) as this one is the same capacity as the original filter available in the 1970's.
For cars such as Series 4 Spiders or others with limited engine bay access, the genuine Alfa branded filter (EN046) is more suitable.
