Dundon Motorsports 3.8L Intake Runners - 981 GT4
Designed to fit:
- 2016 Porsche Cayman GT4 (981)
Using science and engineering to increase performance is what Dundon does. The Dundon 981/991 3.8L Intake Runners are no exception. Through careful design of the intake runner geometry they were able to add 30+ peak wheel horsepower on top of their already potent race headers and tune. By extending the torque curve they increased power substantially all the way to redline, over 100whp gains at 7850rpm over both our headers/tune and stock.
