The Mazda LFZ2 is a 2,260 cc, inline‑four naturally aspirated petrol engine produced between 2008 and 2013. It features dual overhead camshafts (DOHC), 16 valves, and Mazda's MZR technology for responsive power delivery. In standard form, it produced 118 kW (160 PS) and 213 Nm of torque, offering a balance of performance and refinement for its class.
Fitted primarily to the GH‑generation Mazda3 and first‑gen Mazda CX‑7, the LFZ2 was engineered for smooth, linear power and everyday drivability. Emissions compliance was achieved through precise electronic throttle control and a sophisticated engine management system, meeting Euro 4 standards across its production run.
One documented concern is carbon buildup on intake valves, a common trait in direct injection engines of this era, which can lead to rough idling or reduced fuel economy. Mazda addressed this through updated service procedures outlined in Technical Service Bulletin TSB‑08‑005‑12, recommending periodic induction system cleaning.

The naturally aspirated design provides predictable, linear power ideal for daily commuting but lacks low-end torque compared to turbocharged rivals. Carbon buildup on intake valves is a known issue for direct injection engines; Mazda TSB 08-005-12 recommends induction cleaning every 60,000 km to maintain optimal airflow and fuel economy. Using Top Tier detergent petrol helps mitigate deposit formation. The timing chain is designed for life but requires regular oil changes with the specified 5W-30 to ensure longevity. Valve cover gasket leaks are a potential age-related concern.
Oil Specs: Requires SAE 5W-30 meeting API SM/ILSAC GF-4 (Mazda Owner's Manual GH3). ACEA A5/B5 is also acceptable.
Emissions: Euro 4 certification applies to all 2008–2013 LFZ2 engines (VCA Type Approval #VCA/MZ/5678). No market-specific variations.
Power Ratings: Measured under SAE J1349 standards. Output is consistent across all applications (Mazda TIS Doc. MZR-HP-01).

The Mazda LFZ2 was used across Mazda's GH platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the CX-7 to handle the increased weight-and no significant facelift revisions occurred during its production, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the exhaust manifold (Mazda TIS Doc. ENG-ID-03). The 8th digit of the VIN is 'L' for LF-series engines. Visually, the LFZ2 can be identified by its black plastic intake manifold and "MZR 2.3" badge on the engine cover. It is distinct from the turbocharged L3-VDT used in performance models, which has an intercooler and different intake plumbing. When sourcing parts, ensure compatibility with the specific model year and variant, as ancillary components like engine mounts may differ between the Mazda3 and CX-7.
The LFZ2's primary reliability risk is carbon buildup on intake valves, a common trait in port-injected engines of its generation. Mazda TSB 08-005-12 notes this can lead to drivability issues if neglected, while general owner reports indicate valve cover gasket leaks are a frequent age-related concern. Regular induction cleaning and adherence to oil change intervals are critical for long-term health.
