First I would like to say "Thank You" to those who created and maintain this site.I was looking for information on what brand of spark plugs are in the Vibe. (2004) Are there ant recommendations on replacements?
Lots of threads on this topic. Basically you have the best plugs in the marketplace already in your vehicle. Do not change heat range unless you have done major engine mods.
