The 618005C-4 Manley Piston Rings are an exceptional upgrade for your Subaru Impreza WRX or STI (Evo VIII-IX) engine, specifically designed for engines with a bore size of 85.5mm. These piston rings are manufactured with meticulous precision, ensuring a perfect fit and optimal performance in your engine.
The set includes four piston rings: two compression rings, one oil control ring, and one oil scraper ring. The compression rings, marked with an '8.5' on the outside, are designed to seal the combustion chamber effectively, preventing combustion gases from escaping and enhancing overall engine efficiency. The oil control ring, marked with an '8', is responsible for managing oil consumption by controlling the flow of oil between the cylinder walls and the piston skirts, thus reducing oil consumption and promoting better engine efficiency. The oil scraper ring, marked with a '5', is responsible for collecting excess oil and directing it back into the crankcase, ensuring proper lubrication and preventing oil sludge formation.
Manley piston rings are renowned for their superior quality and durability. They are made from high-quality materials, such as chrome molybdenum and nickel alloys, which offer excellent resistance to wear and tear, high-temperature strength, and excellent sealing properties. The rings are also precision-machined to ensure a perfect fit, ensuring a tight seal between the piston and the cylinder wall.
In conclusion, the 618005C-4 Manley Piston Rings are a high-performance upgrade for your Subaru Impreza WRX or STI engine. They offer improved sealing, reduced oil consumption, and enhanced engine efficiency, making them an excellent choice for enthusiasts looking to optimize their engine's performance.
