Hi all. I'm new to the forum. I just purchased an '05 XC70 with 118k on the clock. I have no idea if the spark plugs have ever been changed and am going to do that shortly. My question for everyone is, should I replace the coils at the same time? I'm not familiar the the individual coil arrangement and don't have any idea of what the service interval is.
Thaks for your help!
