CP Piston & Ring Set for Toyota 4AG 16V - Bore (82.0mm) - Size (+1.0mm) - CR (9.0) - Set of 4

CP Pistons is well-known for building strong, reliable internal engine components for performance applications. This forged piston and ring set is specifically made for the Toyota 4AG 16V engine, offering an updated solution for rebuilds or performance builds. These pistons are designed to handle increased stress and heat compared to stock cast pistons, making them a solid choice for enthusiasts looking to get the most out of their 4AG engine.

This set includes four pistons, each measuring 82.0mm in bore diameter and are 1.0mm oversize, which is useful if your engine block requires a slight hone or has been previously bored. The compression ratio is set at 9.0:1, a common target for naturally aspirated or mild forced induction setups that balances power with pump gas compatibility. Forged from high-strength aluminum alloy, these pistons are built to withstand the demands of higher performance levels, offering improved durability and resistance to detonation.

When rebuilding your Toyota 4AG 16V engine, using a set of forged pistons like these from CP Pistons ensures you're starting with a well-built foundation. Proper installation, including ensuring the cylinder bores are clean and within tolerance for the 1.0mm oversize, is key to achieving optimal performance and longevity. Always refer to the manufacturer's installation instructions for specific details regarding ring gap, piston-to-wall clearance, and assembly procedures.
