The BorgWarner AirWerks S300 turbine housing with a 1.10 A/R is specified for S300-series T4 turbochargers and supplies the turbine-side geometry required for proper exhaust flow. Intended for forced-induction assemblies, it accepts standard T4 turbine flanges and supports high-flow exhaust routing. Use it as a direct-fit replacement or component when a 1.10 A/R S300 housing is required.
