The Range Rover 20 H(EFI) is a 4,394 cc, V8 naturally aspirated petrol engine produced between 2002 and 2005. It features sequential electronic fuel injection (EFI), pushrod valvetrain (OHV), and two valves per cylinder. In standard form it delivers 210 kW (286 PS) and 420 Nm of torque, providing smooth, traditional V8 performance with strong low — end pull.
Fitted to the L322 Range Rover during its early production phase, including the HSE and Vogue trims, the 20 H(EFI) was…

All production years (2002–2005) meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/5432).
The Range Rover 20 H(EFI) is a 4,394 cc V8 naturally aspirated petrol engineered for full-size luxury SUV applications (2002–2005). It combines sequential electronic fuel injection with a robust pushrod architecture to deliver smooth, linear power and strong low-rpm torque. Designed to meet Euro 3 emissions standards, it prioritizes drivability and reliability over high specific output.

The Range Rover 20 H(EFI) was used exclusively in Land Rover's L322 platform with longitudinal mounting. This engine received platform-specific adaptations—reinforced engine mounts and revised accessory drive routing—and from mid‑2004 the crankshaft position sensor was upgraded, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
The 20 H(EFI)'s primary reliability risk is crankshaft position sensor failure on early builds, with elevated incidence in high-ambient-temperature regions and frequent short-trip driving. Land Rover internal quality data from 2005 indicated a measurable uptick in intermittent no-start complaints before 80,000 km, while UK DVSA records show no significant emissions-related MOT failures linked to this engine. Thermal stress and oil degradation accelerate component fatigue, making oil quality and interval adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 20 H(EFI) offers smooth, torquey V8 performance with robust architecture, but early models (2002–2003) had crank sensor concerns. Mid-2004 revisions improved durability. With proper maintenance—especially oil changes using 10W-40 STJLR.03.5001—well-cared-for examples can exceed 250,000 km reliably.
Top issues include crankshaft position sensor failure, oil sludge from infrequent oil changes, intake manifold gasket leaks, and water pump coolant leaks. These are documented in Land Rover SIB LTB00187(04) and TIS service procedures. Oil quality and driving pattern significantly influence longevity.
The 20 H(EFI) powers the early L322 Range Rover (2002–2005) in HSE and Vogue trims. It is a pushrod V8 distinct from the later DOHC Jaguar-sourced AJ-V8 engines. All meet Euro 3 emissions with sequential EFI and secondary air injection.
Limited tuning potential due to OHV architecture and conservative ECU. Stage 1 remaps typically yield +10–15 kW safely. Bolt-on upgrades (exhaust, cold air intake) offer modest gains. Significant power increases require camshaft or displacement changes, which are uncommon due to complexity.
In a L322 Range Rover, expect ~16.5 L/100km (city) and ~11.2 L/100km (highway), or ~21 mpg UK combined. Real-world mixed driving typically yields 18–23 mpg UK. Fuel consumption is higher than modern turbocharged engines due to displacement and architecture.
No. The 20 H(EFI) is a non-interference engine. If the timing chain fails, piston-to-valve contact will not occur, reducing the risk of catastrophic damage. However, chain replacement is still recommended at 160,000 km as preventive maintenance.
Land Rover specifies 10W-40 mineral or synthetic oil meeting STJLR.03.5001 (or newer). This viscosity ensures proper lifter and cam lubrication in the OHV system. Change intervals should not exceed 16,000 km or 12 months.
