Hi, iv owned a subaru in the past but never a WRX so a little knew to it. i have a 2006 WRX 2.5 and the only modifications i have so far is a COBB cutback exhauhst. Im mechanically inclined and looking to change my oil and oil filter as well as my spark plugs and wires. kinda OCD when i buy a car i guess. Feel like i have to change every kind of filter or fluid in it. Im planning on buying synthetic oil and an OEM oil filter from a subaru dealership. I have no idea if i should get OEM spark plugs and wires or go with other ones. Any information or suggestions for my oil and spark plug changes or any other kind of maintenance would be greatly appreciated. thank you!!
