ICP20.5 Ignition Switch

The ICP20.5 Ignition Switch from QuickCar Racing Products is a high-performance ignition control unit built specifically for serious racers and dedicated engine builders. Whether you're running a naturally aspirated V8, turbocharged platform, or high-RPM competition engine, this ignition switch handles the critical task of managing starter engagement and ignition circuits with the reliability that motorsports demands. Purpose-built for drag racing, road racing, and engine swaps, this component eliminates the reliability issues of stock ignition switches that weren't designed for repeated high-load cycling or extended performance use.

The ICP20.5 delivers industrial-grade durability through robust electrical contacts, sealed construction that resists moisture and vibration, and a compact footprint that integrates seamlessly into race car wiring harnesses. Unlike stock automotive switches, this unit is engineered to handle the sustained amperage draw of high-output alternators and powerful starter motors without voltage drop or contact degradation—critical when every fraction of a second matters in competitive timing. The reinforced housing and heavy-duty terminals ensure long service life even under extreme underhood temperatures and constant electrical cycling typical in performance applications.

This ignition switch is ideal for engine swap projects, race car builds, and any custom automotive application where factory switching gear falls short of performance demands. Installers appreciate its straightforward integration into custom harnesses and compatibility with both traditional points-style and modern electronic ignition systems. Weighing 1.35 lbs with compact dimensions, it mounts easily in tight engine bays without sacrificing accessibility for maintenance or future modifications—a must-have for builders who demand reliability without compromise.
