Granatelli 87-88 Oldsmobile Cutlass Supreme 6Cyl 3.1L MPG Plus Ignition Wires

If you're working on a 1987-1994 GM vehicle like a Buick Century, Chevrolet Cavalier, or Oldsmobile Cutlass Supreme, these Granatelli MPG Plus ignition wires are a solid option for replacing your old, worn-out set. These wires are built to deliver a strong, consistent spark from the coil to the spark plugs, which is crucial for proper engine combustion and overall performance. When your original wires start to degrade, you might notice rough idling, hesitation, or even a decrease in fuel economy, and replacing them with a well-built set like these can help bring your engine back to life.

Granatelli uses a high-resistance core wire with a silicone jacket to ensure durability and effective suppression of radio frequency interference, helping to keep your electronics running smoothly. The wires are designed to fit right, making installation straightforward for most DIYers. This set is specifically tuned to help optimize the spark energy, potentially leading to improved throttle response and a more efficient burn in the combustion chamber.
