6 PCSNEW -- DENSO #4503 PLATINUM T T Spark Plugs -- PK16TT

work without issue

The set was OEM or better quality for a good price. They were not pre-gapped but with a little patience I set the appropriate gap for all six. Installation on the back side of the horizontally opposed V6 in the 2004 Acura MDX was a little bit of a pain but certainly not the worst job I've had to do. Engine turned right over and I don't have any apparent knock or misses. Don't forget to use a little dielectric lube on those coils though! And if you see oil pooled around the spark plug, the spark tube seals are bad. You replace those along with the valve cover gaskets. And you may as well do the intake plenum gasket set as well. That's next on my radar since I did have oil in two of my spark tubes.

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.
