APR is pleased to present the Stage 3+ High-Flow, CNC-Ported Performance Cylinder Head for the 2.0T FSI (EA113) Engine (AXX, BWA and BPY). Through specific Stage III+ calibration changes, this directly translates to a +70 HP gain over APR’s existing Stage III Turbocharger System on 93 (R+M)/2 octane fuel and up to +126 HP on race fuel!

APR’s engineers have optimized the FSI head with proprietary, computer-controlled porting conducted on APR’s in-house 5-Axis Centroid CNC machine, our engineers have increased airflow by 17% on the intake ports and an additional 12% on the exhaust ports. The engine’s boost-to-airflow ratio is reduced by roughly 10% while also reducing intake air temperature and alleviating backpressure. As a result, the spark knock threshold is extended up to 7 degrees allowing for a substantial increase in power. Read More
