Carry ignition energy from the ignition system to every spark plug with an ACCEL spark plug wire set from the SuperStock 4000 series, part number 4041K. It is listed for many V8 applications, among them the 1966-1978 Dodge Charger (V8-6.3L / V8-6.6L / V8-7.2L) and 1967-1974 Chevrolet Camaro (V8-5.7L), at one set per vehicle. See the Buyer's Guide tab for the full list of applications and engine codes.
ACCEL designed its SuperStock 4000 series to upgrade an OE ignition system for high spark delivery in street-driven applications. The 450°F-rated silicone jacket is extruded over a tightly woven, high-strength fiberglass braid. That braid sits over EPDM (ethylene propylene diene monomer) inner insulation with high dielectric strength. ACCEL states this construction gives ignition wire performance that exceeds SAE specifications.
ACCEL catalogs this as a universal-fit spark plug wire set. Its resistance and boot temperature rating are both listed as meeting or exceeding OE. Signs that plug wires may need replacing include misfires, rough idle, and cracked, hardened, or burned insulation. If worn wires are the cause, these ACCEL wires replace that part of the ignition circuit. Country of origin: Vietnam.
What core and insulation do these ACCEL plug wires use?
The 8mm wire has a carbon graphite core. EPDM inner insulation is covered by a fiberglass braid and a 450°F-rated silicone jacket.
What type of boots and terminals does the 4041K set have?
The set uses 90-degree silicone boots with stainless steel plug terminals. ACCEL lists the boot temperature rating as meeting or exceeding OE.
Which vehicles is this spark plug wire set listed for?
It is listed for many V8 applications, such as the 1967-1974 Chevrolet Camaro (V8-5.7L) and the 1966-1978 Dodge Charger (V8-6.3L / V8-6.6L / V8-7.2L). See the Buyer's Guide tab for the full list.
What are signs my spark plug wires may need replacing?
Common signs are misfires, rough idle, hesitation, or wires with cracked, hardened, or burned insulation. Diagnose first, because plugs, coils, or other ignition parts can cause similar symptoms.
Do these wires help with radio interference?
ACCEL lists RFI suppression for street-driven applications as a feature of this SuperStock 4000 series set.
