The number for a Napa Gold is 1356. This filter is a little longer than the stock size but equal in all other regards. Excellent filter & have used them myself. Am currently using Baldwin filters. The size that matches the 1356 is B1402. While researching this I discovered that Baldwin has a slightly longer filter model B1431 of which I was unaware. My filter locates in a particular way that allows for extra length without issues. I like to have the maximum available capacity for engine oil.
