OEM Distributor Cap - Points - Chev 8 Cylinder #DR976

A distributor cap sends high secondary current from the rotor and coil to the spark plug OE equivalent materials, which promote longer product life Provides superior performance and reliability Fast and easy installation The Wells Vehicle Electronics distributor cap receives high secondary current from the rotor and the coil; each ignition wire is connected to the cap and those wires complete the current path to the spark plug. When it is not replaced, the towers on the distributor cap will either oxidize or corrode, creating a high secondary resistance which can result in rotor and ICM (Ignition Control Module) failure, reduced mileage, CEL (Check Engine Light) illumination, catalytic converter failure or a failed emission test. Wells Vehicle Electronics distributor caps are designed to meet or exceed Original Equipment (OE) specifications in form, fit and function. Every component either matches or improves on the OE design to ensure fast, easy installation, superior performance and reliability.
