From 1992 to 2002, the company’s factories produced the 2.0-liter V6 Mazda KF-DE engine, which was installed on European versions of well-known models like the 323, Xedos 6, and Xedos 9. For the Japanese market, cars with index KF-ZE were modified to produce 160–170 horsepower.
K8-DE, K8-ZE, KF-ZE, KJ-ZEM, KL-DE, KL-G4, and KL-ZE are all members of the K-engine family.
The engine was mounted on:
- Mazda 323 BA in 1994 – 1998;
- Mazda Xedos 6 CA in 1992 – 1999;
- Mazda Xedos 9 TA in 1992 – 2002.

Disadvantages of the Mazda KF-DE engine
Keep an eye on the cooling system because this aluminum block is terrified of overheating;
These power units frequently start using oil after 100–150 thousand runs;
There are lubricant leaks from beneath the valve covers at roughly the same runs;
The timing belt shifts every 80,000 kilometers, but the valves hardly ever bend when it breaks;
Hydraulic lifters can travel up to 50,000 kilometers using subpar oil.
