My question is should I only replace cylinder 6 ignition coil or just do all since I'm there?

Also will be swapping out all sparks
why not swap the ignition coil to another cylinder to determine if you have a spark plug issue or an ignition coil issue and save yourself some money ?
Going to swap the sparks passed 30k anyways. But I will trouble shoot the ignition
