Hi yes velocity stacks let dirt in
Its a trade off back in the day for HP
Fine mesh was sometimes used to keep Canaries out
On CRs all the air ports are too close to the outside
So when pods are installed they plug these ports
Which cause running and tuning issues
Google CR velocity stacks and you will see how they got around this
If using pods you have to carve them in order to free up the port
SUDCO sells 29 mik parts
Jets are common most dealership's can source them
