Supertech Toyota 4AGE 16V 81.50mm Bore 30.5mm Comp Height 11:1 CR Pistons - Set of 4 (Excl Rings)

Supertech is well-known for making solid internal engine components, and these pistons for the Toyota 4AGE 16V engine are a great example of their work. If you're rebuilding or upgrading your 4AGE, these pistons are built to handle the demands of a performance engine. They feature an 81.50mm bore and a 30.5mm compression height, designed to work with your existing or modified 4AGE block and connecting rods.

These pistons are forged, meaning they start as a solid block of aluminum that's heated and hammered into shape. This process makes them incredibly strong and durable, far more so than cast pistons. This strength is crucial for engines that see higher RPMs or increased cylinder pressures. The 11:1 compression ratio is a notable bump over stock, which can lead to improved power and throttle response, especially when paired with appropriate tuning and fuel. You'll need to source piston rings separately, as they are not included with this set of four pistons.

When installing these pistons, it's important to ensure your cylinder bores are properly honed to match the piston skirt design and to allow for correct oil film adhesion. Proper ring gap setting is also critical for performance and longevity. These pistons are a solid option for anyone looking to build a reliable and powerful 4AGE engine.
