Send ignition-coil voltage cleanly to each spark plug wire with the Standard Ignition Distributor Cap DR-446. It is a direct-fit replacement for the listed applications, including the 1975-1977 Chevrolet Camaro, Nova and El Camino, the 1975-1977 Chevrolet C10 and GMC C15, the 1975-1977 Checker Marathon, the 1975-1976 Oldsmobile Cutlass and the 1977-1979 Pontiac Parisienne.
The cap covers the distributor and carries high voltage from the rotor to the plug wire terminals, so each cylinder's spark plug receives its spark.
- Quality control: Standard Ignition describes itself as a global manufacturer of original equipment ignition products. It maintains quality control through the whole manufacturing process, from componentry to finished product.
- Reinforced housing: The cap is made of high dielectric strength, glass/mineral reinforced polyester resin. This material is intended to reduce carbon tracking and give greater resistance to electrical breakdown.
- RFI resistors: Where specified, RFI resistors help suppress radio static and potentially damaging voltage spikes.
- Brass terminals: Where available, solid brass terminals help make better connections and resist electrical pitting and corrosion.
Signs this part may need replacing: cracks, carbon tracks or corroded terminals inside the cap, engine misfires, hard starting, or rough running. These symptoms can have other causes, so diagnose the ignition system first. If a worn cap is the cause, this part replaces it.
This cap fits 54 Buick, Checker, Chevrolet, GMC, Oldsmobile and Pontiac applications. See the Buyer's Guide tab for the complete list and engine details.
