These Denso spark plugs fit perfectly in a 2007 Honda Ridgeline V6 and, along with new ignition coils, cured the P030x misfire errors. Based on the condition of the old plugs, I think they were the main cause. I’d say these plugs are identical to the originals, but frankly the old plugs were so worn, with so much of their electrodes missing, that I can’t really tell. I did inspect the gaps and all six plugs were correct. After replacement, the engine ran smooth again and the misfire errors did not return.
