11 maj 2018 · This is a comparison of a cold heat range plug (left) versus a much hotter heat range plug (right). Notice how the distance between the ceramic and the spark plug shell on the hotter plug requires heat to travel a farther distance, which maintains more heat in the spark plug.
1 paź 2004 · Spark plug heat range is a function of your driving conditions. For all Corvette SBs regardless of power rating or type of ignition, AC heat range "5" or equivalent is best for street and highway driving.
The spark plug heat range only indicates the rate that the spark plug dissipates its firing end heat to the engine. A hotter heat range spark plug has an insulator design with a longer heat flow path to the metal shell of the plug.
Using the correct heat range is key to getting the performance you want out of your engine. For most vehicles, the manufacturer-recommended spark plug and heat range is the best option. Consult your owner’s manual for the right spark plug for your car.
28 cze 2024 · Discover the mysteries behind spark plug heat ranges in vehicles! Unravel how they impact heat dissipation, combustion efficiency, and engine durability. Learn to choose the right range to prevent pre-ignition troubles and enhance performance.
1. Stay cool enough to avoid pre-ignition and/or electrode destruction. 2. Run hot enough to burn off combustion deposits that would otherwise collect at the firing tip. 3. Adapt to specific engine characteristics and widely varying driving/load conditions.
