The ACDelco 41-148 Spark Plug utilizes advanced iridium technology to deliver optimal performance and reliability for your vehicle's ignition system. Iridium composition offers a high melting point and great strength, providing excellent wear resistance and durability. This material also contributes to stable engine idle, reliable cold starting, quick acceleration, and smooth overall performance. Designed as an exact replacement for original components, this spark plug is laser-welded for precision and reduced wear, increasing its durability. It features a three-piece fired-in suppressor seal that meters spark energy for long electrode life, prevents combustion leakage, and blocks radio frequencies that could affect vehicle electronics. ACDelco spark plugs are pre-gapped to the correct specification from the factory. This spark plug is compatible with the 2019 Chevrolet Corvette 6.2L V8. It is important to use the vehicle selector tool to verify fitment for other applications. Always refer to your owner's manual for recommended spark plug change intervals.
