Why these are good choices:
* OEM Equivalents: These are often cited as direct replacements for the original factory spark plugs, meaning they're designed to work optimally within the engine's parameters.
* Reliability and Availability: Both Champion and NGK are reputable brands with readily available plugs.
Before purchasing, always double-check your owner's manual or consult a parts store using your vehicle's VIN. The manual will specify the exact factory recommendation.
Other factors to consider:
* Copper vs. Platinum/Iridium: Copper plugs are generally less expensive and have a shorter lifespan, while platinum and iridium plugs are more durable and can last longer. For a 5.2L engine, the increased cost of platinum/iridium might not be justified unless you're doing extremely high mileage.
* Heat Range: The heat range of a spark plug is critical. Using the wrong heat range can lead to misfires, pre-ignition, or other issues. Sticking with the manufacturer's recommendation is crucial here. Your owner's manual or a parts store will help you confirm the correct heat range.
In short, start by looking for Champion RC12YC or its NGK equivalent. Confirm the heat range and any other specifics with your owner's manual or a trusted parts professional before making a purchase.
