Got your eye on a Screamin’ Eagle® or 120R H-D® engine? Our Zip Kits are the quick and easy way to simplify installation and power tuning on an EFI equipped big engine!

Zipper’s Performance Products has developed ThunderMax maps and performance intake systems specifically for these engines. High flow ThunderMax throttle body/manifolds are mated with our MaxFlow air cleaner kit, ensuring enough airflow for these engines to reach their full potential. Just install the IAC, TPS and fuel rail assembly from your original system to the ThunderMax throttle body, install the pre-mapped ThunderMax ECM and you’ll be ready to go (these Zip Kits include high flow injectors; kits for ’99-’01 models include a fully dressed throttle body and our Marelli conversion components). Our high resolution ThunderMax ECM with AutoTune takes the hassle out of AFR tuning. Just install the Zip Kit and you’re ready to ride—it really is that easy!

For 2008-up TBW Touring models – All you need is a ThunderMax # 309-362, as maps are available for these engines. If an oversize throttle body is desired, Zipper’s recommends using Horse Power Inc’s Throttle-by-Wire Throttle Body. Visit www.HorsePowerInc.net to learn more.
