HKS Super Boxer Racing Oil
Fits Most Models with Horizontally Opposed Engines (FA, EJ, FB Series)
52001-AK130
Overview:
The HKS Super Boxer Racing Oil 0W-20 is a premium synthetic engine oil designed specifically for sports vehicles equipped with horizontally opposed engines, such as Subaru's FA, EJ, and FB series. This high-performance oil provides exceptional protection and lubrication, ensuring your engine operates smoothly under both everyday driving and high-load conditions.
Ideal for enthusiasts running bolt-on turbo setups or factory turbocharged engines with increased boost, this oil delivers superior fluidity at low temperatures for immediate circulation upon startup. It also offers enhanced protection against engine wear and noise reduction, making it a reliable choice for performance and longevity.
Key Features:
HKS Super Boxer Racing Oil combines advanced formulation and technology to meet the demands of modern turbocharged horizontally opposed engines. Key features include:
- 0W-20 viscosity grade optimized for genuine performance and fluidity at low temperatures
- Superior High-Temperature High-Shear (HTHS) viscosity surpassing standard oils for enhanced protection under extreme conditions
- Strong oil film strength and appropriate viscosity to reduce engine noise during cold starts
- Formulated to prevent Low-Speed Pre-Ignition (LSPI), critical for direct injection turbo engines
- Low molybdenum content to reduce deposit formation and maintain engine cleanliness
- Anti-fatigue resistance properties to extend engine life under high stress and load
- Compatible with stock grade #W 40 oils and withstands maximum temperatures up to 140℃
- 100% synthetic base for consistent performance and durability
- Specifically tailored for horizontally opposed engines such as FA20 (supercharged or bolt-on turbo), EJ20, EJ25, and FB series engines
Construction & Design:
The HKS Super Boxer Racing Oil is formulated using advanced synthetic base oils combined with proprietary additive technology. This blend ensures optimal viscosity stability and film strength across a wide temperature range, protecting engine components from wear and thermal breakdown. The low molybdenum formula minimizes friction while preventing harmful deposits, supporting cleaner combustion and longer engine life.
Its design focuses on rapid oil circulation immediately after engine start, reducing wear during cold starts and maintaining smooth engine operation. The oil’s resistance to LSPI makes it especially suitable for modern direct injection turbocharged engines, which are prone to this damaging phenomenon.
Installation & Fitment:
This product is a direct replacement engine oil suitable for most vehicles equipped with horizontally opposed engines requiring 0W-20 viscosity. It fits naturally into the existing oil system without any modifications or special procedures.
- Compatible with factory turbocharged and bolt-on turbo setups
- No special tuning, cutting, or drilling required
- Ideal for vehicles using FA, EJ, and FB series engines
