What type pickups to replace silhouette?

Hi guys I’ve got an early 2000’a (I think it’s an 04 or 06 I forget) HSH silhouette. I believe it has the dimarzio virtual paf’s. I love the neck pickup but the bridge doesn’t have enough bite. I would like to replace it with an evh Wolfgang. What spacing do I need for this guitar? F spaced? Standard?

Anything else I need to be aware of when changing these pickups? Thanks
