The Dist. Cap & Rotor Kit for 4-Cylinder engines by PERTRONIX IGNITION (MPN D604609) is a precision distributor cap and rotor assembly designed for ignition system upgrades and replacements on Pertronix 4-cylinder side exit distributors. This socket-style kit serves enthusiasts, mechanics, and rebuilders who need reliable spark distribution for engine restart, performance tuning, or preventive maintenance. The non-vented design ensures clean, consistent operation in diverse driving conditions.

Engineered with brass terminals and a screw-down mounting system, this distributor cap and rotor assembly delivers robust electrical contact and secure fastening that resists vibration and thermal cycling.
