1354489085 Bosch Spark-Plug Suppressor

The Spark Plug Suppressor from Bosch (MPN: 1354489085) is sourced from Spain and has supplier-listed dimensions of 45 x 105 x 105 mm. It is typically used within the Electrical & Lighting > Engine Electronics > Ignition Leads category of automotive replacement parts. Dimensions are provided by the supplier and may include packaging dimensions. Ignition leads, also known as spark plug wires, deliver high-voltage electricity from the ignition coil to the spark plugs, initiating combustion within the engine cylinders. These multi-strand copper core cables are insulated with silicone or PVC to prevent voltage leakage and withstand high temperatures. Internal resistance is tightly controlled to maximize spark energy and ensure consistent engine firing. Leads are routed from the distributor or coil pack, following engine geometry, and terminate with a conductive terminal securely fitted to each spark plug. Proper length and resistance values are critical for optimal engine performance and emissions control.
