The JE Pistons six‑piston kit for Audi S4 2.7L twin‑turbo applications is a purpose‑built replacement for the 2.7L S4 TT. Forged in the USA from 2618 aluminum, JE’s FSR forging reduces skirt width and friction while the kit’s included wrist pins, locks and JE Pro Seal rings ensure reliable assembly. Accumulator grooves and optional skirt coating help control ring flutter and improve sealing for consistent power delivery in boosted setups.
