Gaskets, nuts, studs, clamps, and bracketry are also included to facilitate installation. Due to the complexity of installation, it is recommended that this kit be installed by an experienced performance shop mechanic. Proper software tuning is essential, and users should contact their preferred tuner for a software solution. Additionally, fueling upgrades are required for the BOSS 600, and an upgrade for engine connecting rods and head studs is recommended for optimal performance and reliability. Important Fitment Note: This kit DOES NOT FIT EUROPEAN GEN3 B8 VEHICLES. It is exclusively designed for EA888.1 and EA888.2 engine codes.
