Granatelli 91-93 BMW 535i/iS 6Cyl 3.4L Performance Ignition Wires

This product includes a set of Granatelli performance ignition wires, designed for the 1991-1993 BMW 535i and 535iS models equipped with the 3.4L 6-cylinder engine. These wires are built to replace your old, worn-out spark plug wires, which are crucial for delivering the electrical current from the ignition coil to the spark plugs. When your original wires start to degrade, they can cause misfires, rough idling, and a general loss of power, so replacing them with a well-built set like these can help restore your engine's performance.

Granatelli Motor Sports uses a high-resistance core wire with a silicone jacket for these ignition wires. This construction helps to suppress radio frequency interference (RFI), which can affect your car's electronics, while also providing durability against heat and abrasion under the hood. The direct-fit design means these wires are made to connect to your existing coil and spark plug terminals without modification, making installation more straightforward. Ensuring a strong, consistent spark to each cylinder is key for efficient combustion and optimal engine operation.
