The K-series came in a variety of capacities/displacements and was the only petrol engine ever fitted to the Rover 25 / MG ZR out of the factory.
In the Rover 25, the K-Series was available as a 1.1 16v, 1.4 16v, 1.6 16v, 1.8 16v and the 1.8 VVC 16v flavours. All the engines bar the VVC are basically the same with a few key differences. The VVC has a more elaborate valve control system to increase power output.
Servicing items such as filters and spark plugs will be common across all non-VVC versions.
