CTS Turbo B5 S4 MAF Housing 85mm

The CTS Turbo 85mm MAF Housing is engineered for B5 Audi S4 owners running modified turbo setups requiring greater airflow capacity. This larger diameter housing reduces restriction through the intake path, accommodating the demands of upgraded turbos and performance tuning. Precision-machined construction ensures accurate sensor placement and maintains proper MAF signal integrity. Direct bolt-in installation replaces the restrictive factory housing, making it essential for builds pushing beyond stock boost levels. Suits 1999-2001 B5 S4 models with biturbo V6 powerplants.
