The Bar-Tek 2.5L TFSI DAZA & DNWA High Boost ULTI Kit is an engine reinforcement solution designed for demanding tuning and high boost applications for the 2.5 TFSI DAZA and DNWA engines used in Audi RS3 and TTRS models. The complete system is designed to withstand extremely high cylinder pressures, high boost pressures, and continuous heavy loads, where original components become a limiting factor.
