Buyer must verify compatibility: Spark-plug requirements can vary within the same vehicle by engine, VIN, ignition system, emissions package, production date, heat range, and specified gap. Confirm ACDelco CR43TS / GM 19354425, tapered seat, 0.43-inch reach, 5/8-inch hex, and the required gap against the original plug or a VIN-based parts catalog before ordering. Send us your VIN, year, make, model, and engine size if you would like help checking compatibility. Inspect the gap before installation: ACDelco spark plugs are manufactured with a preset catalog gap, but every plug should be inspected for shipping or handling damage. Confirm that approximately 0.044 inch / 1.12 mm is correct for your exact engine. Do not force or pry against the center electrode; replace any damaged or incorrectly specified plug. Before Installation

• Allow the engine and cylinder heads to cool completely before removing the old plugs.
• Remove dirt and debris from each spark-plug area before loosening the original plug.
• Compare the part number, reach, seat, hex, terminal, and electrode design with the original plug.
• Start each replacement plug by hand to help prevent cross-threading.
• Use the vehicle manufacturer's specified installation torque.
• Inspect the plug wires, boots, distributor components, and ignition coils while servicing the plugs.
• Professional installation is recommended.
