Prices may varyThe manufacturer's Safety Data Sheet classifies this product with one or more GHS Category 1 health hazards — the most severe tier. The hazard statements in quotes below are the verbatim GHS language from the SDS, as required by OSHA's Hazard Communication Standard. The line under each statement translates the GHS classification into plain language.
GHS Category 1 aspiration toxicity — thin, oily liquids can slip into the lungs if swallowed, causing chemical pneumonia.
GHS Category 1 eye damage — classified as causing irreversible eye damage on contact.
If swallowed, inhaled, or splashed in eyes:
Call Poison Control immediately at 1-800-222-1222 (US, 24/7, free) and have the product container with you. Poison Control's standing guidance is to not induce vomiting after chemical exposure; they will direct first-aid steps based on the specific product.

TL;DR PEA-formula aerosol for GDI engines, applied through the air intake · not a fuel-tank additive. PEA confirmed as the active. Brand testing claims up to 46% deposit removal in one hour, and the broad owner consensus backs GDI-specific efficacy. DANGER signal word, Prop 65, and H318 serious eye damage at mixture level · protective eyewear required for the spray step.
CRC GDI IVD targets gasoline direct-injection engines, where intake valves accumulate carbon that fuel-tank additives cannot reach · GDI injectors bypass the valves entirely. The active is PEA, the most studied detergent class for intake valve deposits. Delivered through the air intake via dual-action straw; no manifold removal required. The brand states up to 46% IVD reduction in one hour from internal testing; no independent SAE paper on file. Owners report improvement on GDI-specific symptoms, and the product is well-reviewed on Amazon. Every 10,000 miles.
Best for GDI or turbocharged engine owners with rough idle or throttle hesitation from intake valve carbon. Skip if you consistently run Top Tier gasoline · that detergent package already addresses deposit formation. Skip for severe misfire codes · professional cleaning is the right call, not a single aerosol treatment.
DANGER from health-classified H-codes. H318 (serious eye damage) at mixture level · protective eyewear required for the spray step. H317 (skin sensitizer) also present; gloves recommended. Do not induce vomiting if swallowed · H304 aspiration hazard; seek medical attention. Prop 65 warning applies. The product combusts in the engine · exhaust byproducts are the environmental endpoint.
The Safety Data Sheet for CRC GDI IVD Intake Valve & Turbo Cleaner carries a DANGER signal word, with classified hazards including H222 (extremely flammable aerosol); H280 (contains gas under pressure; may explode if heated); H302 (harmful if swallowed). The Amazon listing also carries a California Prop 65 warning. See the PPE breakdown above for use-case-specific guidance translated from the SDS hazard codes.
CarCareTruth scores CRC GDI IVD Intake Valve & Turbo Cleaner at 5.7 out of 10 on the composite CCT score, with a health sub-score of 1.0/10. The CCT score blends real-world effectiveness, ingredient health impact pulled from the manufacturer's safety sheet, and environmental footprint against a published category rubric. See the methodology link on this page for the full scoring breakdown.
Per the Safety Data Sheet ingredient disclosure: Contains polyether amine, hydrotreated petroleum distillates (CAS 64742-47-8, 64742-80-9), alkyl aminoester, lubricating oil base. Propellant: liquefied petroleum gas.
