From 1992 to 2002, the Japanese plant produced the Mazda KL-ZE 2.5-liter V6 engine, which was used in regional versions of well-known models like the MX-6, Efini, and Eunos. This motor had a different intake manifold and a higher compression ratio than the KL-DE.
K8-DE, K8-ZE, KF-DE, KF-ZE, KJ-ZEM, KL-DE, and KL-G4 are all members of the K-engine family.
The engine was mounted on:
- Mazda Capella GW in 1997 – 2002;
- Mazda Cronos GE in 1992 – 1997;
- Mazda Efini MS-6 GE in 1992 – 1994;
- Mazda Efini MS-8 MB in 1992 – 1998;
- Mazda Eunos 800 TA in 1993 – 1998;
- Mazda MX-6 GE in 1992 – 1997.

Disadvantages of the Mazda KL-ZE engine
This series’ engines are thought to be fairly dependable;
Keep an eye on the cooling system because the engine’s aluminum block is terrified of overheating;
Oil frequently seeps out from under the valve covers on runs longer than 100,000 kilometers;
The timing belt resource is around 80,000 km, but when it breaks, the valve typically does not bend; hydraulic lifters can knock up to 50,000 km and cannot withstand inexpensive lubrication.
