What is the primary function of spark plug wires?

Spark plug wires carry high voltage electricity from the ignition coil to the spark plugs. This electrical charge ignites the fuel-air mixture in the engine's cylinders, which is essential for the engine to run.

What makes these NGK wires suitable for my BMW 320i?

NGK uses a tinned copper core wire and premium silicone insulation, which are designed to handle the high voltage requirements of your specific European model. They also include RFI suppression and a watertight seal on the boots.

How do I know if my spark plug wires need replacing?

Signs of worn spark plug wires include a rough idle, misfires, reduced engine power, poor fuel economy, or difficulty starting. Visually inspecting the wires for cracks, brittleness, or burn marks can also indicate they need replacement.

Product Details

This is an NGK spark plug wire set specifically for your 1980-1983 BMW 320i. These wires are crucial for getting a strong spark from your spark plugs to the engine's cylinders, ensuring smooth running and proper combustion. If your old wires are cracked, brittle, or showing signs of wear, replacing them with a well-built set like this from NGK can make a noticeable difference in how your engine performs.

NGK uses a tinned copper core wire, which is what certain European models like yours originally came with, to handle high voltage currents effectively. The outer jacket is made of high-temperature silicone, and the inner insulation uses EPDM and silicone to maintain excellent dielectric strength, meaning it keeps the electricity where it needs to be. NGK also builds in RFI suppression right at the spark plug and distributor connectors, which helps prevent radio frequency interference. The spark plug boots are sealed to the cable with silicone for a watertight connection, keeping moisture out.
