OEM Spark Plug Part Number?

[cryptolime]

what's with all the different spark plug part numbers? Honda says DILKAR8P8SY . i think that's the Japanese part number though. NGK America says 92411 for the Si (0.030" gap) . is that correct?

they would be the same? or do I need to order direct from Honda?

Both numbers represent the same plug. NGK has always had 2 different numbers like that. No idea why. The long number you referenced is printed on the plug itself, and the box will usually have both as I recall from my days working in a garage.

Side Note: Once you do certain upgrades, the NGK Iridium (ILZKAR8H8S/Stock No. 95112) with a slightly smaller gap is also recommended.

I had to tighten my gap on my 10th Gen si plugs. I was sitting at 333whp. Made her run so smooth.
