Supertech Toyota 4AGE 16V 81mm Bore 30.5mm Comp Height 11:1 CR Pistons - Set of 4 (Excl Rings)

If you're rebuilding the engine in your Toyota 4AGE 16V, these Supertech forged pistons are a solid choice for boosting performance. Designed for an 81mm bore, they feature a 30.5mm compression height and a 11:1 compression ratio, which is a notable increase over stock. This higher compression ratio helps to extract more power from your engine, making it a popular upgrade for those looking to get more out of their 4AGE.

These pistons are forged from high-strength aluminum, a process that makes them much more durable and resistant to detonation than cast pistons. This added strength is crucial when increasing compression or planning to push the engine harder. The 81mm bore size is specific to certain 4AGE configurations, so double-check your engine's bore before ordering. Keep in mind that this set includes the pistons only; you'll need to purchase piston rings separately to complete the installation. This is a common practice when building engines, allowing you to select the exact ring set that best suits your build and tuning goals.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and procedures. Proper installation is key to ensuring the longevity and performance of your engine build. These pistons are intended for off-road use and are not CARB approved, meaning they cannot be shipped to California. Ensure you are aware of your local emissions regulations before purchasing.
