	No new bike responds to simple intake and exhaust upgrades like a new Harley-Davidson® motocycle! But today’s new EFI bikes are more complicated to modify. Gone are the days of changing a few jets plugging in a new ignition module—EFI has changed that. So we developed the Zip Kit for stock 88” EFI Big Twins that includes a Zipper’s high flow air cleaner, performance exhaust and our cutting-edge ThunderMax EFI Controller. The ThunderMax ECM is pre-mapped for the intake and exhaust system supplied, so there are no worries about dyno tuning because we’ve done it for you! And the ThunderMax gives you the flexibility of future upgrades with just the download of a new map. Just bolt-on / plug-in the Zip Kit and enjoy the power, performance and drivability of the most highly refined EFI system on the market! Ordering is easy! Simply, choose the kit for your bike and the exhaust system that you desire. Don’t see what you’re looking for here?
