.044 is the default gap of this plug. I replaced this 3461 with the same one. The old ones had about 75,000 miles and were leaking around the ceramic resulting in rust colored stains on the insulator on the plug itself. They all looked about the same. It's time to replace them. It's an easy task, and the plugs rotate up to 13 ft/lbs, in case you're wondering.
