Sorry if this questions been answered a billion times already, I tried searching but couldn't find exactly what I was looking for. I have a del sol S model and I was considering doing the spark plug changes myself, I really don't want to have to take it to a shop to have it done. I have a torque wrench, and was wondering if someone could share the torque specs and gap setting information with me. I also hear that automotive companies already choose the 'best' spark plug brand for their motors if so which spark plug should I be going with? Any insight would be greatly appreciated. Thank you in advance.
