Spark Plug Question...

[gunner1]

Can someone please tell me the difference between these two part numbers for ngk sparkplugs? BPH-N-10 AND BPZ8H-N-10. Both of these plugs are listed in my manual for my 115hp outboard Mercury, but the price difference is between $4 and $8 per plug!

the Z is either platinum or iridium

The Z means it has an inductive radio suppressor in the plug... Less interference on a radio.

You can try an automotive store for spark plugs for OBs. They are ususally the cheapest, over marine stores or dealers.
