M12 x 1.25 Stainless Steel 316 Threaded Plug Fitting with Copper Washer – Slim Round Allen Key Head – Metric Thread Sealing Plug for Hydraulic, Fluid and Industrial Systems

You won’t regret it. The LV sounds insane, and the bike is totally transformed. Especially at low-speed/low-throttle. Nate’s tune also really mellows out the engine braking which, IMO, was borderline violent in stock form. Don’t forget to plug the AIS line. Some people use a block-off kit, some people shove a marble in the line. I chose to use a vacuum cap and block the ports on the solenoid and airbox. No matter what, you need to make sure to do that. I just remembered that you’ll need a second O2 sensor bung plug because the tune will eliminate all O2 sensors. The LV comes with one, but you need 2. You need an M12x1.25 plug. I used this one: https://www.amazon.com/dp/B08F4YJPGZ You can unplug the O2 sensor and just tape off the connector. I chose to make my own male delete plug, but it’s not totally necessary.
