Product details
Control the original vacuum-operated exhaust valves on the listed naturally aspirated Ferraris using the matching Forza kit. Check particulate-filter equipment first: a GPF-equipped car can react differently to valve override, even when the model name appears in the application list.
Before you order
Confirm the exact Ferrari exhaust actuators and GPF equipment before ordering. Ask PMB to confirm the current kit contents, including remote quantity.

- Installation is reversible when performed using the supplied connections.
- Match the original valve actuation, solenoid count, polarity and plugs before fitting.
- Exact transmitter quantity and any required adapter plugs should be confirmed for the supplied kit.
- Powered through the matching original vacuum-solenoid connection; no wire cutting or splicing is specified.
- Supports factory-controlled operation and an open-valve setting. Mode availability depends on the exact controller and vehicle.

Use restrictions
Use only the operating modes permitted by the vehicle-specific Forza instructions. Forza excludes an always-closed mode on turbocharged applications. A valve controller does not establish emissions or local noise compliance.
With over 20 years of parts experience, PMB Performance can help check the application. Share your VIN and photos or references for the component being replaced before ordering if the match is uncertain.
