Supertech Toyota 4AGE 16V 82mm Bore 30.5mm Comp Height 11:1 CR Pistons - Set of 4 (Excl Rings)

Forged from high-strength aluminum alloy, these Supertech pistons are built to handle the demands of a performance-tuned Toyota 4AGE 16V engine. With an 82mm bore and a 30.5mm compression height, they are designed to achieve an 11:1 compression ratio, offering a notable increase in power and responsiveness over stock components. This set includes four pistons, ready for your engine rebuild.

The choice of forged aluminum is key here; unlike cast pistons, forged blanks are heated and then struck with a die to shape them, creating a stronger, more durable internal grain structure. This makes them significantly more resistant to detonation and fatigue, which is crucial when you're pushing an engine harder. The 11:1 compression ratio is a popular choice for naturally aspirated 4AGE builds, striking a good balance between increased power output and pump gas compatibility, though careful tuning is always recommended to maximize performance and prevent issues.

This set is for the pistons only; you will need to source your own piston rings separately. Ensure you select rings compatible with an 82mm bore and the correct oil ring groove width for your specific application. Proper installation, including correct ring gap and piston-to-wall clearance, is essential for the longevity and performance of these components. Always refer to your engine's service manual or a trusted performance tuning guide for precise installation specifications.
