Bluetooth analyzer, a 5/16" quick-connect fitting, and Oetiker crimp clamps. Connectivity options include Bluetooth for app integration (iPhone and Android apps available) and a 5v analog output suitable for JB4 or flash tuning devices. This kit is specifically designed for the Audi S4, with compatibility extending to various other Audi and Porsche models including the A4, A5, A6, A7, Q5, and Macan variants.
