Designed to deliver genuine viscosity performance, this oil ensures rapid circulation immediately after engine start, providing superior protection under both low and high temperature conditions.
Ideal for enthusiasts running bolt-on turbo setups or factory turbocharged engines with increased boost, this oil offers enhanced durability and noise reduction while maintaining excellent fluidity in cold starts. Whether you drive daily or push your vehicle hard on the track, HKS Super Boxer Racing Oil helps safeguard your engine against wear and low-speed pre-ignition (LSPI).
Key Features:
This advanced racing oil incorporates cutting-edge technology and formulation to meet the demands of high-performance horizontally opposed engines:
- 100% synthetic base for consistent performance and engine cleanliness
- Viscosity grade 10W-40 optimized for both low-temperature fluidity and high-temperature stability
- Superior High-Temperature High-Shear (HTHS) viscosity exceeding standard oils for robust oil film strength
- Low molybdenum formula reduces deposits and enhances anti-fatigue resistance
- Effective protection against Low-Speed Pre-Ignition (LSPI), critical for direct injection turbo engines
- Reduces engine noise at low temperatures through appropriate viscosity and oil film strength
- Maximum allowable operating temperature up to 140℃ for high-load conditions
- Specifically engineered for horizontally opposed engines such as Subaru FA20 (supercharged or bolt-on turbo), EJ20, EJ25, and FB series
Construction & Design:
The HKS Super Boxer Racing Oil is formulated with a balanced blend of synthetic base oils and advanced additives to maintain viscosity under extreme conditions. Its low molybdenum content and anti-fatigue agents help extend engine life by minimizing wear and preventing oil breakdown during high-stress driving.
