The Bar-Tek 2.5 TFSI High Boost ULTI Kit is an engine internal kit designed for demanding tuning and high boost applications for Audi RS3 and TTRS 2.5 TFSI engines. The package is based on a combination defined and tested by Bar-Tek, where JE® forged pistons and BAR-TEK® steel connecting rods are dimensioned to withstand high boost pressures, high cylinder pressures, and continuous loads.
The kit is intended for situations where the original internal components no longer meet reliability requirements. The parts have been selected to work together according to the 2.5 TFSI engine's structure and load profile, providing a stable and technically controlled foundation for powerful engine builds.
