Hi guys, So ever since I bought my lovely 05' Civic, I've been wanting to do a bit of maintenance to it, seeing as it has run over 86000 miles now. This includes replacing all filters and replacing my spark plugs. After having checked some guides, I feel fairly confident that I can replace the spark plugs myself. However I thought it best to ask here before proceeding, seeing as there are some inconsistencies in the guides.. Namely: - Whether or not to use anti-seize compound like Copper Ease and how to apply this to the spark plugs. - Normal or Iridium Spark plugs? Recommended brand? - Spark plug gap distance (and is it even necessary?) Thanks!
