[HD FBOY]

Put the zippers on tonight. It uses the HD back plate so if you don't like the Zippers AC you can swap to the K&N. The K&N filter with Backing plate uses a rubber velocity stack so it went off the list for me. The only thing I don't like about the Zipper is that it sticks out a good inch further than the stock AC. I also considered the Ness Big Sucker. This one also sticks out further than stock.
