er mag een beetje veranderd worden:

2. Each year modifications to the engine can be homologated. Details will be delivered to the FIA before January 1st of the year in question, and a complete engine delivered before the first of February of that year.

3. The elements of the engine which can be changed in this way on an annual basis, are:

- ports;
- combustion chamber shape;
- valve size, shape, and angle;
- piston crown (the weight of the piston must remain the same, as must piston ring position and compression height);
- camshaft profiles and valve actuation kinematics;
- intake manifolds;
- injector nozzles (not injector actuator);
- spark plugs;
- changes to the cylinder head consequential upon and limited to those resulting from the above;
