Hey I changed out the coil packs and it runs fine, don't worry about your fuel filter it should last you the duration of time that you own the car. I went ahead and replaced all 4 because my tuner said he wouldn't charge me labor, ran me about 370.00$ for 4 coils w no labor. Oem from a subaru dealership.
