Notes: (1) Airbox required. (2) Minimum exhaust length (as raced) is 16 3⁄4” as measured from the back side of the header flange, around the right side of the header, connector and pipe to the first weld at the end of the divergent cone. new IAME X30 ignition, airbox and main bearings are all improvements to the engine platform, and these will be at the option of the team and competitor for the balance of the 2021. The NGK BR10EG and B10EG spark plug will be allowed for the balance of the 2021 season.
