Wix 1021 does not cross ref, it is a commercial application filter.
I'd take i down to Napa and match it up. Start with a 1069 or the longer version of that filter.
It sure looks like a wix 51069 to me.... I am doing my winterization
this weekend, and I am going to see if they match up. I would rather have a wix on there anyhow. Buying the k&n is throwing money away.
