The following models may require the cover plates if you want to run a velocity stack. Check out this video to help determine if you will need the cover plates! - How do I know if my Honda Shadow needs Cover Plates?
Will NOT Fit:
Cover Plates are intended to work with our Velocity Stacks and Performance Tuning Kit or Complete Carb Performance Rebuild Kit.
If you are unsure if you need these or not, take a look at the pics. There is a pic of the stock aluminum cover for the valve with hose connected to it, if you have one of these on the top of each head cover, then you can remove them and replace with the cover plates.
