I just replaced mine today, heh... Its a a bosch filter, part #71028, 86 325, it should be the same exact filter number... It cost me 21.00$ including/ tax at the local autopart international store... Just keep in mind that even after you depressurize the fuel system the filter is still full of fuel! Good luck! want to change the fuel filter on my 87 325. anything special i should be aware of? can i just go get one from a local auto zone or is there some better brand to look for or things to watch out for? TIA of course
