Are IZFR6K11 and IZFR6K13 NGK laser iradium plugs interchangeable?what is the difference between them.....which one to use in civic reborn
have you checked the owners manual? The NGK website lists these for Honda Fit and Honda Element...
K11 are for civic, k13 are for city. Minute gap distance makes them different but yes both are interchangeable. I would still suggest going with the oem recommendation depending upon vehicle ie k11 for civic reborn.
