: The insulator features multiple ribs to prevent electrical "flash-over" (current leakage across the insulator surface), a common issue in high-humidity environments or when spark plug wires are worn. This design ensures reliable spark delivery even under adverse conditions. Investing in an OEM-grade component like the DENSO
Many drivers ask: "Why should I pay a premium for the 5285 when a $2 copper plug works?" The answer lies in three critical areas: performance, efficiency, and durability. : The insulator features multiple ribs to prevent
