60k Service Maintenance Package for 2004–2021 Subaru STI

The 60,000-mile mark is a vital maintenance milestone for your 2004–2021 Subaru STI. Our complete service package includes all necessary OEM-quality parts and premium fluids to keep your EJ257 engine and driveline operating at peak performance. Designed specifically for the STI, this kit supports long-term reliability, drivability, and factory-level performance.

Included Components

(x1) Subaru PCV Valve
Maintains crankcase ventilation efficiency to reduce oil contamination and crankcase pressure.
(x4) MOTUL Gear 300 75W90 100% Synthetic Ester Gear Oil (1L Containers)
High-performance synthetic gear oil for the 6-speed manual transmission, offering exceptional protection and thermal stability under aggressive driving conditions.
(x1) MOTUL 90 PA Limited Slip Differential Gear Oil (1L Container)
Formulated specifically for limited-slip differentials, this oil ensures smooth, quiet operation and long-term durability.
(x2) Coolant 50/50 Pre-Mix (1 Gallon Containers)
A ready-to-use coolant solution that protects against corrosion, scale buildup, and temperature extremes.
(x1) MOTUL RBF 600 DOT4 Brake Fluid (0.5L)
Race-grade fluid with high boiling points to maintain brake performance during spirited or high-load driving.
(x1) MOTUL 8100 5W30 ECO-NERGY Motor Oil (5L)
A high-quality synthetic engine oil designed to improve fuel efficiency and protect internal engine components in turbocharged applications.
(x1) WIX Oil Filter
Premium filtration for reliable oil cleaning, ensuring optimal engine protection.
(x1) Oil Drain Plug Washer

OEM iridium spark plugs designed specifically for the EJ257, delivering reliable ignition and long service life under boosted conditions.

Key Service Tasks – Expanded

PCV Valve Replacement
The Positive Crankcase Ventilation valve helps control internal pressure and routes combustion gases back through the intake. Replacing it helps prevent oil leaks, improves idle stability, and reduces emissions.
Transmission Fluid Change – MOTUL Gear 300 75W90
Old gear oil can degrade and lose its protective qualities, especially under heat and load. Replacing it with MOTUL Gear 300 provides smoother shifting, reduced wear, and extended life for the 6-speed transmission.
Rear Differential Fluid Change – MOTUL 90 PA
Your STI’s limited-slip rear differential relies on the correct oil to maintain proper operation and prevent chatter. MOTUL 90 PA ensures quiet engagement and protects against thermal and mechanical stress.
Coolant Flush and Refill – 50/50 Mix
Coolant breaks down over time, losing its ability to protect against corrosion and overheating. A flush and refill with fresh 50/50 coolant keeps the EJ engine and turbocharger running at optimal temperatures.
Brake Fluid Flush – MOTUL RBF 600 DOT4
Brake fluid absorbs moisture over time, lowering its boiling point. Replacing it with high-temp RBF 600 improves pedal feel and braking performance—especially critical in high-speed or high-load scenarios.
Engine Oil & Filter Change – MOTUL 8100 & WIX Filter
Clean, high-quality oil is essential for turbocharged engines. MOTUL 8100 5W30 offers excellent protection and thermal resistance, while the WIX filter ensures contaminants are properly captured. A new drain plug washer prevents leaks.
Spark Plug Replacement – NGK SILFR6A (x4)
Fresh iridium plugs restore ignition efficiency, reduce misfires, and support smoother engine operation. These NGK plugs meet factory specifications for turbocharged EJ engines and are ideal for both stock and tuned setups.
