CD-1 C/T Spec Ignition Kit

The DAYTONA SENSORS CD-1 C/T Spec Ignition Kit is a complete capacitive discharge (CD) ignition system designed for high-performance engine applications requiring reliable, precise spark timing. This ignition kit combines the CD-1 ignition box with a matched coil assembly to deliver consistent spark energy across a wide RPM range, making it ideal for vintage motorsports, hot rod builds, and engines where modern electronic control isn't available or desirable.

Capacitive discharge ignition technology stores electrical energy in a capacitor and releases it through the coil in a rapid pulse, producing a hotter, shorter spark duration than conventional inductive systems. This approach reduces point erosion, minimizes fouling on spark plugs, and maintains consistent ignition timing even at high RPM or under lean fuel conditions. The CD-1 box and integrated coil specification are engineered to work as a matched pair, ensuring optimal energy transfer and voltage regulation. The kit's compact form factor (6.4 x 5 x 16.8 inches) allows flexible mounting in confined engine bays typical of classic vehicles and custom builds.

This system is widely favored by builders restoring carbureted engines, classic muscle cars, and vintage racing applications where points-based ignition was original equipment. The CD-1 Spec kit addresses the limitations of aging contact-point distributors—weak spark at high RPM, inconsistent timing drift, and excessive maintenance. Installers should verify distributor compatibility and existing spark plug wire terminations before purchase, as this kit replaces the ignition timing and energy generation components while typically retaining the original distributor body.
