The 99.75mm piston ring set for Subaru EJ257 WRX STI is a high-quality replacement part designed specifically for engines with a 0.25mm compression ring clearance (CR). This set includes 10 piston rings, each measuring 99.75mm in diameter, and is compatible with Subaru's SC7442 pistons and engine model number 730656666588.
The set includes two compression rings, two oil control rings, and six skirt rings. The compression rings are designed to seal the combustion chamber and maintain engine compression, while the oil control rings help prevent oil from entering the combustion chamber. The skirt rings, on the other hand, provide support to the piston and prevent side-to-side movement.
These piston rings are made from high-quality materials, such as nickel-chromium-molybdenum alloy, to ensure durability and long-lasting performance. They are also precision-engineered to fit perfectly into the piston grooves, ensuring a tight seal and reducing the risk of engine oil leaks.
The 0.25mm CR of this piston ring set is ideal for engines that have been modified to increase performance, as it allows for more compression and improved engine efficiency. However, it is important to note that using the wrong compression ring clearance can cause engine damage, so it is crucial to use the correct clearance for your specific engine application.
In summary, the 99.75mm piston ring set for Subaru EJ257 WRX STI is a high-quality replacement part that is designed to provide a tight seal and improve engine performance. It is compatible with SC7442 pistons and engine model number 730656666588, and is ideal for engines with a 0.25mm compression ring clearance.
