About this part

Product Details

These Granatelli MPG Plus ignition wires are built with a silicone jacket and copper conductor, designed to handle the electrical demands of your 1989-1995 Cadillac DeVille's 4.9L V8 engine. They replace your old, worn-out wires, which can lead to misfires and a loss of power. By ensuring a strong spark reaches each cylinder, these wires help your engine run more efficiently.

The copper conductor inside these wires offers good conductivity for a reliable spark, while the silicone outer jacket provides protection against heat and abrasion. This combination helps maintain consistent performance over time. Installing a fresh set of spark plug wires is a common maintenance task that can make a noticeable difference in how your engine idles and accelerates.

This set is specifically made for the 4.9L engine found in models like the DeVille, Concours, and DTS during these years. If you're noticing rough idling, hesitation, or a general lack of responsiveness, a new set of ignition wires like these from Granatelli is a solid option to consider.
