Just picked up an 04 9-3 Arc wanted to change the oil and perform a tune up. What is the correct oil filter? I was on the parts store website and they had 2 engines listed. FI Turbo DOHC and MFI Turbo DOHC. I'm new to the Saab universe. I looked in the manual couldn't find which one it was vhecked rhe vin codes still nothing. Can some please enlighten me as to which engine I have. I know mine is the high output turbo. Also can anyone tell me if the rotar lots on eBay are any good?
