Stratified K04 Turbo Upgraded Wastegate Actuator – EA888 and EA113

Description:

Improve boost control and maximize the performance of your K04 turbo with our direct bolt-on upgraded wastegate actuator.

The factory K04 actuator uses a soft 0.5 bar spring, which can limit boost response and contribute to boost taper at higher RPM. Our upgraded actuator is supplied with three interchangeable spring options to suit your setup:

• Yellow: 0.8 bar
• Blue: 1.0 bar (pre-installed)
• Red: 1.2 bar

Benefits include:

• Faster boost response
• Improved boost control
• Reduced boost drop-off at high RPM
• Direct bolt-on installation

Compatible With:

EA888 & EA113 K04 Turbos

Dimensions (since there are lots of K04 variants on the market, please verify these fit your particular K04)

• Actuator Shaft Length: 196mm, thread length: 50mm
• Mounting Bolt Spacing (center to center): 34.40mm

Note: This actuator requires custom ECU calibration to operate correctly. We offer custom tuning to fully optimize its performance.
