Benefits:

• Aggressive Combustion Chamber Purging: Rapidly penetrates and breaks down crusty, hardened carbon structures layered over piston crowns and combustion walls.

• Carburetor and Throttle Restoration: Instantly flushes delicate fuel ports inside carburetors and cleans oil film residues off throttle body butterflies to preserve uninhibited airflow.

• Remediation of Sticky Intake Valves: Completely dissolves heavy, sticky varnishes that restrict valve seating alignment, restoring full cylinder compression and recovering lost engine torque.

• Idle Stabilization and Smoothness: Drastically cures severe engine shaking, rough idling vibration, and cold-starting lag linked to poor induction balance.

• Optimized Ignition Efficiency: Promotes complete thermal breakdown of air and fuel mixtures, curbing rich exhaust wastage and significantly lowering tailpipe smoke.

How to Use:

1. Run the engine until it reaches normal operating temperature, then remove the primary air cleaner assembly to fully expose the carburetor throat or throttle intake.

2. Shake the 368g ACDelco X66A canister vigorously to maximize internal propellant pressure and mix the active agents.

3. With the engine running (have an assistant slightly depress the gas pedal to maintain low RPM and prevent stalling), spray the conditioner in controlled bursts directly into the throat.

4. Heavy white smoke will billow from the exhaust tailpipe; this is perfectly normal and indicates the carbon crusts are being incinerated and evacuated.

5. After dispensing the required chemical volume, rev the engine a few times to clear loosened soot, then switch off the ignition and let it hot-soak for 5 to 10 minutes to dissolve valve deposits.

6. Restart the vehicle and drive it normally for a short distance until the white exhaust smoke completely dissipates, then securely reassemble the air filter.

Suitable For:

• Carbureted engines, traditional electronic fuel injection (EFI) throttle bodies, motorcycle power units, and any automotive mechanical system suffering from severe lag, rough idling, or excessive engine carbon buildup.

Note:

• This high-grade fluid is a highly potent corrective and preventative conditioning agent; to maintain maximum mechanical responsiveness and secure completely free valve movement, it is highly recommended to integrate this premium American tune-up spray into your regular major service routine.
