NPR SWG10019-2 Piston Ring Set for Suzuki Engine - 2.3L J23A

The NPR SWG10019-2 is a professional-grade piston ring set designed for the Suzuki 2.3L (140 cubic inch) J23A DOHC fuel-injected engine. This set is manufactured by NPR (Nippon Piston Ring), a leading supplier of OEM-quality internal combustion engine components with over 50 years of experience in precision engine parts manufacturing.

Key Features:

• Engineered specifically for Suzuki Aerio 2.3L J23A engines (2004-2008 model years)
• Premium steel construction for superior durability and performance in modern high-compression engines
• Advanced surface treatments including chrome plating and ferrox coating for reduced friction and wear
• Precision-engineered ring dimensions ensure optimal sealing, reduced oil consumption, and decreased blow-by
• Manufactured to meet or exceed JIS (Japanese Industrial Standard) specifications
• Two-cylinder set configuration (use two sets for complete four-cylinder engine rebuild)

NPR piston rings feature advanced materials and surface treatments designed to handle higher operating temperatures, increased compression ratios, and strict emissions requirements of modern engines. The steel ring design provides reduced radial wall thickness for a lighter, more efficient seal compared to traditional cast iron rings.
