Projected square platinum electrode spark plug — Why it’s better

Why carmakers use projected square platinum electrode spark plugs A Projected square platinum electrode spark plug is built like a double fine wire spark plug except for the ground electrode. The ground electrode has a shorter reach and has a fused square shaped tip of platinum. They’re used in turbocharged engine applications where the car maker requires a “high ignitability” spark plug. They incorporate a platinum square ground electrode placed directly over the center electrode to provide a more focused spark and improved heat dissipation. Advantages of a PSPE spark … Read More
