The CRC Industries GDI IVD Intake Valve & Turbo Cleaner dissolves and lifts deposits from
valve stems and tops without top engine teardown. Especially
needed to remove carbon deposits in GDI engines where fuel additives don’t
reach intake valves, this cleaner contains the highest PEA (polyether amine) detergency
available, says the company. Using this cleaner can help stabilize rough idle, hesitation and stalling; improves airflow and miles per gallon. The formula is safe for turbos, intercoolers and all
gasoline engines.
