GDI Cleaner

Cleans Intake Valves to Restore Power in GDI Systems.

The Problem

In Gasoline Direct Injection (GDI) systems, the fuel is highly pressurized and injected through a common rail line into the combustion chamber of each cylinder below the intake valve. Conventional multi-port systems inject fuel onto the intake valves in the combustion chamber. The conventional systems keep the valves clean, whereas GDI systems do not. Over time carbon will build up on the intake valves and reduce the air/fuel mixture into the cylinders. The deposits that form can cause sporadic ignition failures, lower fuel economy and diminished power.

The Solution

BARDAHL PRO GDI Cleaner is a powerful formula specifically designed for removing carbon and other harmful deposits from the intake valves that accumulate in GDI engines. This product is applied directly onto the intake valves using a professional pressurized system. When applied as directed, it will soften and remove deposits, restoring power and performance.


  • Removes carbon deposits on intake valves.
  • Eliminates hesitation, hard starting, and rough idling.
  • Improves fuel economy, restores performance, and reduces emissions.


Apply with a professional pressurized system or “Bardahl Vac-matic” onto intake valves. Do not pour into the fuel tank. Use 1 bottle every 15,000 miles to maintain optimum performance. Vehicles with mileage over 50,000 or with severe carbon build-up, use 2 bottles per application. Dispose of any used or unused solution in accordance with local, state, and federal regulations.
