Proflow SuperMax Wire, Lead Separator Post Kit, Vertical Mount, High Temp Nylon, Set of 4

Keep plug leads routed cleanly under heat that kills cheaper separators.

• ▸6/6 nylon construction rated to 400°C without distortion
• ▸Non-conductive material eliminates any risk of misfires
• ▸Vertical mount design suits tight engine bay routing
• ▸Pairs directly with Proflow clamp-style wire separators
• ▸Set of four covers a full bank of plug leads

Cheap plastic separators go brittle, crack, and eventually let leads chafe against headers or each other. The 6/6 nylon used here holds its shape and dielectric properties well beyond the temperatures a hard-driven engine produces. At $35.84 for a set of four, it's a straightforward fix that stays fixed.
