I belive around 15-16, depending on if you have coupe or sedan
However your owners manual would know... Also if you look at the
gas pump after filling your tank from empty or close to empty you
may also know...
Quoted from Haynes manual for Sebring/Stratus/Avenger:
The manufacturer does not suggest periodic fuel filter
replacement on 2001 and later models because the fuel filters are
integtated with the fuel pump assembly.
