Need to install a set of Q20PR-U spark plugs which somebody told me that were factory gapped to 0.8 mm, question : if my motor works with regular spark plugs gapped to 11 mm, should the Denso plugs be re gapped to 11mm to work properly. These plugs have a middle internal groove under the tip which provides a tad larger spark than regular ones.
Assume that if the spark is bit larger there's no need to re gap them to 11 mm, but who knows ? Is there someone who has installed them and knows about if thie re gap is needed ? Thanks in advance.
