Mitsubishi Evolution Wastegate Actuator - Go Fast Bits - Internal, Adjustable - '05–'06. A compact, bolt-on internal actuator for Evo 9 that enhances boost control and tuning flexibility.

GFB’s WGA replaces the factory unit with a larger Silicone/Nomex diaphragm using a bead-retention design for greater control authority in a small package. With 18 mm of rod travel and an included spring set (mix-and-match 5–22 psi), it supports precise base pressure setup. A turnbuckle lets you dial in pre-load in minutes without swapping springs, while the encapsulated PEEK spherical rod guide reduces friction and overall height. The short-body design helps cut boost taper and improve response on 2005–2006 Lancer Evolution models.

• 18 mm stroke for wide control range
