Customer's Idea for Filter Use
 
Important Velocity Stack Information:
Velocity Stacks have been proven scientifically and mechanically to give up to 10 to 15% more power. Those that have been successful have done their homework and RETUNED their machines to make their Velocity Stacks work. This includes carburetion and pipes. You will have more air in and more exhaust out. Remember No Air restriction.
