IAG 60K OE Engine Service Package For 2004-05 Subaru WRX

60k Service Maintenance Package for 2004 – 2005 Subaru WRX (Manual Transmission)

At 60,000 miles, routine service is essential to maintain the performance, reliability, and efficiency of your turbocharged EJ205-powered WRX. This maintenance package includes high-quality fluids, filters, and ignition components tailored to 2004–2005 Subaru WRX models with a manual transmission and engine bay–mounted fuel filter.

Note: 2004 and early production 2005 models use a engine bay–mounted fuel filter that is available as an option.Mid-to-late 2005 WRX models transitioned to an in-tank fuel filter, which is not offered with this kit. 

Included Components

• (x1) Subaru PCV Valve
  Supports proper crankcase ventilation, reducing pressure and oil contamination.

 

• (x3) MOTUL MOTYLGEAR 75W90 (1L Containers)
  Synthetic gear oil designed for smooth shifting and extreme pressure protection in 5-speed manual transmissions.

 

• (x1) MOTUL 90 PA Limited Slip Differential Gear Oil (1L Container)
  Mineral-based gear oil optimized for rear limited-slip differentials to minimize chatter and ensure smooth lock-up.

 

• (x2) Coolant 50/50 Pre-Mix (1 Gallon Containers)
  Pre-mixed coolant designed to protect aluminum engine components against corrosion, overheating, and freezing.

 

• (x1) MOTUL RBF 600 DOT4 Brake Fluid (0.5L)
  High-performance brake fluid with extreme thermal stability for consistent pedal feel and performance.

 

• (x1) MOTUL 8100 5W30 ECO-NERGY Motor Oil (5L)
  Full synthetic engine oil engineered for turbocharged engines, offering excellent wear protection and fuel economy.

 

• (x1) WIX Oil Filter
  High-quality filter with durable construction for effective filtration during extended oil change intervals.

 

• (x1) Oil Drain Plug Washer
  Ensures a clean, leak-free seal during oil service.

 

• (x4) NGK BKR6EIX Spark Plugs
  Iridium spark plugs designed for long service life, consistent ignition, and improved combustion efficiency.

 

Optional Components - 2004 - Early 2005 WRX 

• (x1) Engine Bay Fuel Filter
  OEM-style filter for early WRX models, maintaining clean fuel flow and protecting injectors from contaminants.

 

Key Service Tasks – Expanded

• PCV Valve Replacement
  Ensures proper crankcase pressure management. A clean PCV valve reduces oil blow-by, prevents sludge buildup, and supports smooth engine operation.

• Transmission Fluid Change – MOTUL MOTYLGEAR 75W90
  Replaces degraded fluid in the 5-speed manual transmission. MOTYLGEAR 75W90 delivers excellent shear resistance and protection, ensuring smoother shifts and extending transmission life.

• Rear Differential Fluid Change – MOTUL 90 PA
  Fresh gear oil reduces noise and wear in the limited-slip differential. MOTUL 90 PA is specially formulated to reduce chatter and provide consistent lock-up under load.

• Coolant Flush and Refill – 50/50 Pre-Mix
  Coolant deteriorates over time, leading to poor heat transfer and potential corrosion. Flushing and refilling ensures effective engine cooling and long-term system protection.

• Brake Fluid Flush – MOTUL RBF 600 DOT4
  Old fluid absorbs moisture and reduces braking performance. MOTUL RBF 600 offers a high boiling point for improved braking under aggressive or repeated use.

• Engine Oil & Filter Change – MOTUL 8100 & WIX Filter
  Turbocharged engines demand strong oil protection. MOTUL 8100 5W30 and a fresh WIX filter ensure clean lubrication and thermal stability during spirited driving.

• Spark Plug Replacement – NGK BKR6EIX (x4)
  New NGK iridium spark plugs restore ignition precision, improve fuel economy, reduce misfires, and support smoother acceleration.

• Fuel Filter Replacement (Engine Bay Style)
  Critical for early WRX models with a serviceable engine bay–mounted fuel filter. A clean filter ensures reliable fuel flow and protects the fuel system from clogging or injector damage.
