CP Piston & Ring Set for Toyota 4AG 16V - Bore (81.5mm) - Size (+0.5mm) - CR (12.0) Single Piston

Forged from high-strength aluminum alloy, this CP Pistons single piston and ring set is built for the demanding requirements of a Toyota 4AG 16V engine. The 81.5mm bore size, combined with a +0.5mm oversize specification, is designed for engines that have been bored out to accommodate a larger piston diameter, often during a rebuild or performance enhancement. This particular set features a 12.0:1 compression ratio, which is a notable increase over stock, meaning it's intended for builds aiming for improved power output and responsiveness.

CP Pistons are well-known for their robust construction and attention to detail. This set includes the piston and rings, ready for installation. The forged construction offers improved durability and resistance to the stresses of higher compression and performance driving compared to cast pistons. This makes it a solid option for enthusiasts looking to refresh or upgrade their 4AG engine with reliable components.

Please note that this piston set is not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified mechanic to ensure this piston set is the correct choice for your specific engine build and performance goals.
