Audi 2.7 Biturbo Y-pipe is made from strong TIG-welded aluminum and built to replace the factory plastic setup. It includes a flange for the Hitachi MAF sensor and is finished in a wrinkle black powder coat for a clean look. With a 90mm outer diameter and 85mm inner diameter, this part allows better airflow through the intake system.
The pipe bolts directly to the factory or silicone ""lobster claws"" and is designed as a full replacement for the stock Y-pipe and MAF housing. It is important to note that this part works best when the car’s tune is scaled for an 85mm Hitachi MAF.
