Enhance your engine's performance with this Upper Engine & Intake System Cleaner Spray, formulated to remove carbon deposits and restore airflow efficiency in gasoline engines. The advanced cleaning formula targets hard-to-reach areas like intake valves, pistons, and combustion chambers — areas most affected by carbon buildup that cause hesitation, power loss, and rough idling. Its precision aerosol design allows direct application through the air intake or throttle body for fast, controlled cleaning. Ideal for engines equipped with direct or port fuel injection, this spray helps improve throttle response, maintain fuel economy, and extend the life of vital engine components. Each 12 oz (340 g) can delivers multiple cleanings, making it suitable for both preventive maintenance and periodic deep cleaning. Use regularly to keep your engine breathing efficiently and running smoothly.
