Ferrari Testarossa Spark Plug Wire Clips

thingiverse

Factory Spark Plug wire retainers can be tricky to locate in the US, whereas they are readily available in Europe. Factory clips cannot be reused after removal, which is a problem if you need to refinish your valve covers. When removing the original clips, a plastic sleeve remains lodged inside the valve covers. These new retainers easily press-fit into those openings without requiring any modifications. It's theoretically possible to replicate the factory two-piece design using these retainers, but doing so would be complicated and unnecessary. These retainers are nearly identical in size to the factory clips. As evident from the image, you will need multiple units of each type, as Ferrari used smaller clips repeatedly on the cover. I utilized a Markforged Onyx printer with 53% infill and 4 shells to produce these retainers. They turned out incredibly strong and durable, surpassing the strength and durability of the factory ABS injection mold.
