Description
Porsche 981 GT4 Dundon Intake Runners (2015-2016)Using science and engineering to increase performance is what we do. The Dundon 981 991 3. 8L Intake Runners are no exception. Through careful design of the intake runner geometry we were able to add 30+ peak wheel horsepower on top of our already potent race headers and tune. By extending the torque curve we increased power substantially all the way to redline, over 100whp gains at 7850rpm over both our headers tune and stock. Left Graph is Torque at
