The system starts at 80mm and can expand up to 88mm for larger airbox systems. For any given size inlet there is a theoretical maximum flow limit, but in real world testing the actual results are typically around 90%. On the GTI we set out to achieve this limit and hit 90% of the ideal maximum with the APR turbo inlet! This means the turbo doesn't have to work as hard, which translates to lower temperature, and improved performance.

Features

• Increase in flow to 90% of the ideal maximum, lower pressure drop, optimized performance over stock
• Turbo inlet adapter is removable and can be modified for larger turbo setups
• Full system addresses all restrictions between the turbocharger and airbox
• Wire-reinforced hose lined with fluorosilicone for oil and fuel resistance
• Fits 80mm and 88mm airboxes
