Rover 400/45/MG ZS Ignition Components - 2000/2500 KV6 Petrol 6 Cylinder
Two different types of coils were fitted to the KV6 engine range. The earlier system had different coils on each bank (known as Bremi) whilst on the other system all six coils were the same (known as Champion) so it is important to check which system is fitted before ordering parts.
The systems were changed as part of MG Rover's Project Drive around 2002 aimed at increasing the car companies competitiveness. No exact change point is listed but for cars up to a VIN ending 604195 it is likely to be the Bremi system fitted and cars with a VIN after 604196 it is likely to be the Champion system.
