The JE Pistons six‑piston kit for Audi S4 2.7L twin‑turbo applications is engineered as a direct‑fit option for the 2.7L S4 TT. Forged in the USA from 2618 aluminum, the pistons feature JE’s FSR forging to reduce skirt width and friction. The kit includes premium wrist pins, locks and JE Pro Seal rings. Accumulator grooves and optional skirt coating help reduce combustion gas pressure at the rings and limit wear in high‑demand turbo use.
