Once again Iroz motorsport delivers only the highest quality billet hardware for the 8V/8S RS3/TTRS 2.5 DAZA / DNWA. Featuring a high-flow oversized intake plenum. During development we found the OEM unit to leak from the poor designed factory seals. With the use of a performance based silicone o-ring, the leaks are eliminated while increasing overall flow by 25 % over the oem unit. The billet plenum is designed to work in conjunction with the OEM runners or IMS billet runners.
