Engine & Performance Warehouse PR435 Engine Piston Ring Set Standard Bore

The Engine & Performance Warehouse PR435 is a standard bore engine piston ring set engineered to restore proper compression, oil control, and sealing performance in 2.0L and 2.3L L4 DOHC engines. Designed as a direct OE-replacement, this ring set is precision-manufactured to meet or exceed original equipment specifications, making it a trusted solution for engine rebuilds and overhauls.

Piston rings are a critical component of the engine block assembly. When worn rings allow combustion gases to bypass the piston — a condition known as blow-by — the result is reduced power output, increased oil consumption, and blue exhaust smoke. Replacing worn rings with a properly fitted set restores cylinder sealing and returns the engine to factory performance levels.

Key Features:

• Standard bore sizing for direct OE fitment
• Precision-engineered for proper compression sealing and oil control
• Manufactured from high-grade materials including steel and cast iron with performance coatings
• Meets or exceeds OEM quality standards for performance and durability
• Cross-references: 2C5158, S87564
• Compatible with 2.0L–2.3L L4 16V DOHC applications

The PR435 piston ring set is an essential component for any thorough engine rebuild. Proper installation, including ring gap checking and correct orientation, is recommended for optimal results.
