AWD System:
Advanced Symmetrical All-Wheel Drive with Active Yaw Control (AYC) and/or Driver Controlled Center Differential (DCCD).
Manual Transmission Fluid:
Hypoid Gear Oil API GL-4 or GL-5, viscosity typically 75W-90 (consult manual for exact spec).
Transfer Case Fluid:
API GL-5, 75W-90 or manufacturer-specific fluid.
Front Rear Differential Fluid:
API GL-5, 75W-90 or manufacturer-specific fluid.
Audio System:
Factory CD players, cassette players, and AM/FM radios were common. Upgraded systems with more speakers often available.
Traction Control:
Available on later models, often integrated with the AWD system.
Active Yaw Control:
A hallmark feature of the Evo, electronically controlling torque distribution between rear wheels for enhanced cornering stability.
OBD Ii:
OBD-II compliant systems introduced in the mid-90s, allowing for electronic diagnostics.
Oil Change Interval:
Every 3,000-5,000 miles (5,000-8,000 km) or 6 months, whichever comes first, especially for performance driving.
Timing Belt Replacement:
Every 60,000 - 100,000 miles (96,000 - 160,000 km) or 5-7 years. Critical for preventing catastrophic engine damage.
Spark Plug Replacement:
Every 30,000 - 60,000 miles (48,000 - 96,000 km), depending on plug type (copper, platinum, iridium).
Engine Oil Type:
Synthetic 5W-30 or 5W-40 (API SN/SM or higher), depending on climate and driving conditions.
Coolant Type:
Mitsubishi DiaQueen Super Long Life Coolant (or equivalent ethylene glycol-based antifreeze with corrosion inhibitors), typically a 50/50 mix with distilled water.
Engine Reliability:
The 4G63T is generally robust but can be susceptible to rod bearing failure under extreme stress or poor maintenance (e.g., oil starvation, detonation).
Turbocharger:
Oil leaks, bearing wear, or clogged oil lines can lead to turbo failure if not properly maintained. Regular oil changes are crucial.
Clutch:
Clutches can wear out relatively quickly with aggressive driving. Clutch slave cylinder leaks are also common.
Suspension:
Bushings can wear over time, leading to vague handling and noise. Check control arm bushings and sway bar links.
Rust:
Common for older vehicles, especially in areas with road salt. Check wheel arches, rocker panels, and subframes.
Rally Success:
Born from Mitsubishi's success in the World Rally Championship (WRC), designed as a homologation special.
Generations:
The period 1992-2008 spans the introduction of the Evo and its continuous development through the iconic 4G63T era up to the Evo IX.
Key Changes 1992-2008:
Significant advancements in engine power, chassis rigidity, active differentials (AYC/ACD), braking systems, and aerodynamic styling across generations.
