JE Pistons SCION 2AZFE 9:1 KIT Set of 4 Pistons

If you're looking to rebuild the engine in your Scion for higher performance, a set of forged pistons like this JE Pistons kit is a critical component. These pistons are designed to handle the increased stress and heat that come with modified engines, offering a solid foundation for boosted applications or just a more robust naturally aspirated setup. The 9.0:1 compression ratio is a popular choice for forced induction builds, allowing for more boost pressure before detonation becomes an issue.

JE Pistons has been making high-performance engine components for a long time, and this kit is built using their experience. They're forged from 2618 aluminum right here in the USA, which gives them the strength needed for demanding use. You'll find features like their proprietary Forged Side Relief (FSR) design, which helps reduce friction and skirt wear, and an accumulator groove that can improve ring seal. Depending on the specific application, these pistons might also come with a skirt coating to further cut down on friction and noise, plus they include quality wrist pins, locks, and JE's Pro Seal piston rings to ensure a good seal right out of the box.

This kit is for the 4-cylinder 2AZ-FE engine and includes everything you need for a complete set of four pistons. Keep in mind that this kit is not CARB approved and cannot be shipped to California. For any performance engine build, especially those involving forced induction, using well-built pistons like these is key to reliability and achieving your power goals.
