Spark Plug - bproauto (1BP01739AA)

This Genuine Mopar Spark Plug (1BP01739AA) is the high-precision ignition source designed to restore the factory-spec combustion efficiency and cold-start reliability of your engine. While "universal" performance plugs often feature mismatched heat ranges that can lead to "pre-ignition" or carbon fouling, this authentic OEM plug is factory-calibrated to the exact electrical and thermal requirements of your powertrain.

The Advantage That Sets You Apart

• Precision-Tuned Heat Range: Unlike "one-size-fits-all" aftermarket plugs, this Mopar plug is engineered to stay hot enough to burn off carbon deposits during idling, yet cool enough to prevent the "pre-ignition" knocking that occurs under heavy towing or high-speed loads.
• High-Fidelity Precious Metal Core: Crafted with a proprietary electrode alloy designed for "zero-erosion" longevity. It maintains its factory-spec gap through millions of ignition cycles, ensuring your coils don't have to "overwork" to jump the spark—protecting your expensive ignition system from premature failure.
• Total System "Data-Handshake": Designed by the original manufacturer to provide the exact electrical resistance required by your Engine Control Module (ECM). This ensures "clean" signal feedback, preventing the "phantom" misfire codes and radio interference common with non-genuine "multi-fit" plugs.
• Ceramic "Anti-Flashover" Insulator: Featuring a high-density, multi-ribbed ceramic insulator that prevents high-voltage electrical "leakage" to the engine block. This ensures 100% of the energy is delivered to the spark gap for a complete, clean burn—maximizing your fuel economy and horsepower.
• Anti-Seize Plating Technology: The shell is treated with a specialized automotive-grade coating that prevents the "galvanic-welding" common in aluminum cylinder heads. This ensures the plugs remain "serviceable" for future maintenance without the risk of stripped head threads.
• Mopar Certified Protection: Backed by a Mopar 2-Year/Unlimited Mile Warranty, offering a level of ignition-critical accountability and nationwide dealership support that online-only "white-label" brands simply cannot match.
