So I am attempting to replace my air filter... I have "trained" Amazon to search for parts that fit my 2000 Subaru Legacy. Bought a lovely Upgr8 air filter, only to find it is about 3" short in width. I then looked at all of the offerings Amazon had for filters that supposedly fit my vehicle, and they all appear to be about the same size. What gives? Anyone know of a filter that will truly fit my car?
