I’m looking into the Screamin Eagle 64mm throttle body upgrade too! For installation, make sure you’ve got a good set of torx and hex keys. Some folks recommend a torque wrench to avoid over-tightening. Good luck!

Definitely! You’ll also need a gasket scraper and some gasket sealant for a clean install. And don’t forget to disconnect the battery before you start!
