KEY
Service Tasks:
– EXPANDED PCV Valve ReplacementThe 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 75W90Old 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 PAYour 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 MixCoolant 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 DOT4Brake 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 FilterClean, 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.
