    JE Pistons Subaru STI Engine Kit - 100mm Bore, CR 8.5, EJ257 Block & EJ20 Head Integration

    JE Pistons are specifically engineered for extreme applications, including professional competition, where high performance and durability are essential. Crafted from high-tensile strength 2618 aluminum alloy, these pistons are designed to withstand higher compression ratios, extreme boost levels, and heavy nitrous usage. Each piston is meticulously forged for optimized performance, ensuring long-lasting reliability even under the most demanding conditions.

    Key features include application-specific forgings for uniform crown thickness, a contact reduction groove to minimize frictional drag, and an accumulator groove to enhance top ring stability. Additionally, CNC-machined side reliefs and lower support bands provide extra skirt strength, while the included JE ProSeal piston rings and honed pin bores further enhance performance. Whether for custom applications or standard sets, JE Pistons offer unmatched precision and durability, making them the ideal choice for high-performance engines.
