13:1 Piston is recommended to use with 110+ Octane Race Fuel, minimum of 100+ Octane. Pistons are a 3-Ring Design (same as TRX450R Piston), and have two compression sealing rings. We typically recommend 2-Ring Pistons for most racing applications, or other applications where customer / builder is looking for maximum engine power, as 2-ring pistons are lighter weight and have less cylinder wall friction, but 3-ring pistons do offer improved "durability". 3-Ring Pistons offer improved durability due to the 2nd compression ring offers slightly better oil control over after longer duration running periods on the engine (a 2-Ring Piston Design might start burning engine oil due to loss of ring seal / oil control sooner than a 3-ring piston design, as the 2nd compression ring does provide additional oil control to prevent engine oil from getting past the piston rings).Replacement Components:
