I run mine at .55 . at .44 u might burn them faster and something to think about. just cause they come pre-gap I would'nt use that. they can fit a different engine, which one? I dont know only parts counter guy can tell you that. plus durring shipment they get banged around and can close gap some.

Leave it at .044. They're sold as a pre-gapped, oem replacement plug.
