HI I have a ba xr6 n/a with a colder thermostat fpv cold air intake and exhuast and also custom tune from C&V pulling 181.8 rw/kw. I like to known what you think. I service it ever 5000km. If I use a after market fuel filter after 3000km the car has LOST POWER if I use motorcraft fuel filter no problem but every where I tryed to get one no one sells it. Does anybody known were to get one or do I have to go to ford. THANKS
