Precision C4 Fit (1984–1995, including ZR‑1) – Engineered for direct replacement of the auxiliary fan switch on all 1984–1993 models and 1994–1995 ZR‑1s—no modifications required. Manual Low‑Temp Fan Activation – Lets you override factory temps (200 °F on, 185 °F off) for cooler operation under high-load conditions or idle heat buildup Complete Plug‑and‑Play Kit – Includes the switch, wiring harness, all necessary hardware, and instructions for simple installation—whether you’re running one fan or both. Enhances Engine Performance & Longevity – By allowing earlier fan engagement, it reduces thermal stress on your cooling system and helps preserve engine life—especially during hot weather or heavy driving. Versatile Setup Support – Works for single or dual-fan arrangements; optional harness required for certain models (e.g., single-fan C4s) to ensure seamless wiring integration.
