Can I use this as a direct replacement in my SLSA.

If you have a B&C regulator that needs to be replaced this will be a direct replacement. If your RV-12 has a Ducati regulator you will need to order "12 REGULATOR KIT-1" to get the necessary part to convent to the B&C regulator. 

This is not compatable with RV-12iS with 912iS engines.
