Unleash massive performance with a compact design! Our GFB wastegate actuator (WGA) features an industry - first diaphragm design. The Silicone/Nomex diaphragm uses a new bead retention design, achieving the largest effective area with a small outside diameter. This not only reduces the overall size of the WGA but also gives it better control over the wastegate flap, leading to excellent boost control. It's like having full command over your turbo! With an 18mm rod travel, it has the longest stroke, suitable for large internal wastegates or increasing boost pressure without changing springs. The unique pivoting rod guide, machined from PEEK, takes up less height, offers low friction, and has superior wear resistance. It's also the shortest actuator on the market, thanks to detailed design. Adjusting the WGA is a breeze! We provide 3 stainless - steel springs with a range from 5psi to 22psi. And here's the industry - first turnbuckle adjustment. The long stroke allows for more adjustment range of spring pre - load, enabling you to fine - tune base boost pressure in minutes without swapping springs or removing the actuator. Available in bolt - on or universal kits. Check the GFB website for details. This part fits Mitsubishi Lancer Evolution from 2005 - 2006.

Using this wastegate actuator is easy. First, choose the appropriate spring combination from the 3 stainless - steel springs we provide according to your needs. If you need to fine - tune the boost pressure, you can use the turnbuckle adjustment. It allows you to change the spring pre - load quickly without removing the actuator. When installing, make sure it fits well with your Mitsubishi Lancer Evolution from 2005 - 2006. As for maintenance, keep it clean and check the rod guide regularly for any signs of wear. If you notice any issues, replace the parts promptly. Avoid using it in extremely harsh environments to prolong its lifespan.
