Thunder Mfg adapter allows the use of any of several Thunder Mfg. airkits on your bike.
Thunder Mfg.'s adapters are designed for performance. We also strive to make our products easy to install and use. Note that when changing your airkit you will need to use an electronic fuel control system. If you already have a Power Commander you must remap it for the Thunder Airbox. Likewise if you have a Lightning FI or similar your settings will need to be adjusted accordingly.
If you do not already have a Power Commander then you can purchase one here
