CP Piston & Ring Set for Toyota 4AG 20V - Bore (81.5mm) - Size (+0.5mm) - CR (9.0) - Single Piston

If you're rebuilding the engine in your Toyota 4AG 20V, a solid set of pistons is key to getting it running right. This single piston and ring set from CP Pistons is made for a specific bore size and compression ratio, helping you achieve your performance goals. It's designed to fit your 4AG 20V engine, ensuring a proper seal and reliable operation.

CP Pistons are known for their well-built forged construction, which is stronger than cast aluminum. This means these pistons can handle higher cylinder pressures and temperatures, making them a good choice for builds that see more than just daily driving. This particular set is for an 81.5mm bore and is sized at +0.5mm, meaning it's meant to replace a piston that's slightly worn or to achieve a specific clearance in a freshly bored block. The 9.0:1 compression ratio is a common target for naturally aspirated or mild forced induction setups, offering a good balance between power and drivability.

Remember that this piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
