Autolite Spark Plug

[87GNT]

Hello All-

I went to O'Rielly's to get some Autolite #23's but the part number was apparently updated to # 27's. I decided to purchase them and upon arriving home I noticed they are pre-gaped to 40 degrees. I need to set to 27-28 degrees. Did I purchase the wrong plugs and if so where can I buy the correct ones?

Thanks

So the plug is stamped with Autolite 25

I think they sold you the wrong plug. Should say 23.

That plug is too hot for our engines. With the mods you have the Autolite 144 is a better choice. It is between the 23 & 24 in heat range, but has a non-extended tip. I order them from RockAuto as it is a marine engine plug.

In the NGK world the BR6FS (4323) is a cross to the 144.
