Teikoku Piston Ring Co., Ltd. is a Japanese manufacturer of piston rings and cylinder liners with a heritage dating back to the 1940s. The company has long been a trusted OEM partner for major automotive brands such as Honda, Toyota, Nissan, and Subaru, supplying precision-engineered components for both factory assembly and the aftermarket. At JDMshop.eu, Teikoku piston rings represent genuine Japanese quality, designed for perfect fitment and long-term reliability in Honda engines.

Teikoku piston rings – stable compression and superior wear resistance

Teikoku piston rings are engineered to deliver maximum combustion sealing, reduced oil consumption, and consistent performance under extreme thermal and mechanical conditions. The brand utilizes advanced surface treatments — including chrome, molybdenum, and phosphate coatings — to improve resistance to friction, corrosion, and heat. Each set is subject to strict dimensional inspection and vibration testing to ensure precise fit and long-lasting compression stability.

• Compression rings – manufactured from high-grade alloy cast iron or stainless steel, featuring excellent hardness and structural stability. They provide tight sealing even at high RPMs and under the demanding conditions of Honda’s VTEC engines.
• Oil control rings – three-piece, flexible, and highly resistant to sticking or deformation. They efficiently remove excess oil from the cylinder wall, ensuring clean combustion and reduced oil consumption.
• OEM precision – Teikoku piston rings meet the same specifications as factory-installed Honda components. They are used in engines such as D15, D16, F20, K20, R18, and R20, guaranteeing full compatibility and micrometric accuracy.

Teikoku Piston Ring is a recognized name in Asia’s OEM engine component industry. The company continuously develops new surface and metrology technologies, holding ISO 9001 and IATF 16949 certifications. Teikoku products are trusted by professional workshops and rebuilders for both stock and performance applications — from classic D-series to modern K-series Honda engines.
