Heavy Duty Turbo Control Valve - Bosch M4.3

Heavy Duty precision turbo control valve (TCV) from IPD, that provides rock solid boost control and high accuracy restoring power from failing solenoids that are slow and sluggish. Slow spool time and fading boost pressure is common with weak factory solenoids and can rob you of power you didn't know you even lost. It's designed to handle high heat, high pressure, and tough environments, ipd's new turbo control valve was built with longevity in mind. With crisp actuation and precise control you'll regain lost power from poorly operating stock units. Fits all turbocharged Volvo 850's with the Bosch M4.3 motormanagement; T5, R and 2.5T.
