STP Pro-Series intake valve cleaner
Trust STP Pro-Series Intake Valve Cleaner to give your Intake Valves a professional-grade clean. Modern GDI engines spray fuel directly into the combustion chamber. Although this design is great for power and improved gas mileage, it leaves your intake system susceptible to harsh deposit build-up that pour-in fuel additives just can't reach. These deposits can rob your engine of the peak performance and efficiency it once had and, if left untreated, can lead to catastrophic engine failure.
